ROHM Develops the Industry's Smallest* CMOS Op Amp Optimized

　　ROHM has developed an ultra-compact 1.8V - 5V, rail-to-rail CMOS operational amplifier (op amp) - the TLR377GYZ. It is optimized for amplifying signals from sensors such as temperature, pressure, flow rate, used in smartphones, small IoT devices, and similar applications.　　The size of smartphones and IoT devices continues to decrease - requiring smaller components. To accurately amplify small signals as needed in high precision sensing, op amps must improve low input offset voltage and noise performance while continuing to shrink the form factor.　　The TLR377GYZ succeeds in balancing miniaturization with high accuracy (which has been difficult to achieve with conventional op amps) by further evolving proprietary circuit design, process, and packaging technologies cultivated over many years.　　Op amps’ input offset voltage and noise generation degrade amplification accuracy and can be suppressed by increasing the size of the built-in transistors - but at the expense of miniaturization. In response, ROHM developed proprietary circuits which achieve a maximum offset voltage as low as 1mV without increasing the size of the transistors. In addition, proprietary process technology greatly reduce flicker noise, while ultra-low noise is achieved with an input equivalent noise voltage density of 12nV/√Hz by optimizing the resistive components at the element level. Furthermore, the new product adopts a WLCSP (Wafer Level Chip Scale Package) with a ball pitch of just 0.3mm utilizing original packaging technology. This reduces size by approximately 69% compared to conventional products and 46% over existing compact products.　　The IC-mounted conversion board that can replace SSOP6 packages is also offered to support replacement considerations and initial evaluation. Both the new product and conversion board are available for purchase through online distributors. In addition, the high accuracy SPICE model - called ROHM Real Model - is available on ROHM’s website for verification simulations.　　Going forward, in addition to greater miniaturization and accuracy, ROHM will continue to improve op amp performance by reducing power consumption further utilizing proprietary ultra-low current consumption technology.　　Key Product FeatureA shut down function required by mobile devices is built in, reducing power consumption during standby mode.　　Application Examples• Smartphones, compact IoT devices equipped with measurement sensor amps, etc.　　High Accuracy Simulation Models: ROHM Real ModelsROHM Real Models are new high accuracy SPICE models that utilizes original model-based technology to faithfully reproduce the electrical and temperature characteristics of the actual IC, resulting in a perfect match between the IC and simulation values. This ensures reliable verification, contributing to more efficient application development - for example by preventing rework after prototyping. ROHM Real Models are now available on ROHM’s website.　　TerminologyInput Offset Voltage　　The error voltage that occurs between the input terminals of an op amp.　　Flicker Noise　　Noise inherent to electronic components such as semiconductors. Power is inversely proportional to frequency, so the lower the frequency the greater the power. Also called 1/f noise or pink noise. Other types of noise include thermal (i.e. Johnson-Nyquist, white) noise.　　Equivalent Input Noise Voltage Density　　The value obtained by short-circuiting the input terminals and referring the noise voltage density appearing at the output to the input terminals, i.e., since amplifiers have gain (amplification factor), dividing the output noise voltage density by the gain allows for a fair evaluation of the amplifier’s intrinsic noise characteristics.　　ROHM Real Model　　A high-accuracy simulation model that succeeds in achieving a perfect match between the actual IC and simulation values utilizing ROHM’s proprietary model-based technology.

ROHM Develops a Novel VCSELED™ Infrared Light Source that Combines Features of VCSELs and LEDs

ROHM Develops a Novel VCSELED™ Infrared Light Source that Combines Features of VCSELs and LEDs

　　ROHM has established VCSELED™, a new infrared light source technology that encapsulates a VCSEL (Vertical Cavity Surface Emitting Laser) element in a resin optical diffusion material for laser light. ROHM is currently developing this technology for commercialization as a light source for improving vehicle Driver Monitoring Systems (DMS) and In-Cabin Monitoring Systems (IMS).　　To further enhance automotive safety, driver monitoring systems are increasingly being installed in vehicles equipped with Advanced Driver Assistance Systems (ADAS) to detect drowsiness, sleepiness, and distracted driving. In Japan, the Ministry of Land, Infrastructure, Transport, and Tourism (MLIT) has created guidelines that define the design and functions of the system, and in the EU, there are plans to make installation mandatory in all new vehicles sold in Europe from July 2024 onwards. Automakers and suppliers are also developing in-vehicle monitoring systems to detect occupants other than the driver, and there is a growing awareness of the need for high-performance light sources that enable detection systems to function with greater precision.　　In response, ROHM has developed VCSELED™ that achieves high-accuracy sensing. Minimal wavelength temperature variation combined with a wide emission beam angle make it ideal not only for in-vehicle monitoring systems, but also contribute to improving the accuracy and performance of inspection systems for robots and industrial equipment as well as spatial recognition and ranging systems.　　VCSELED™ extends the beam (irradiation) angle similar to LEDs by combining a high-performance VCSEL element and light diffusion material to enable sensing over a wider area with higher accuracy than VCSELs. What’s more, the light emitting element and light diffuser are integrated into a compact package, contributing to smaller, thinner applications.　　The VCSEL element used in VCSELED™ features a narrow emission wavelength bandwidth of 4nm, approximately one-seventh that of LEDs. This characteristic improves resolution performance on the receiving side while eliminating the red glow often associated with LEDs. At the same time, a wavelength temperature variation of 0.072nm/°C - less than one-fourth that of LEDs (0.3nm/°C) - allows for high-accuracy sensing unaffected by temperature changes. Furthermore, the response time when emitting light is 2ns, approx. 7.5 times faster than LEDs, contributing to higher performance in ToF (Time of Flight) applications that use infrared light to measure distance.　　ROHM is working on commercializing VCSELED™ as a new technology brand for infrared light source components. Prototype samples is available for purchase now, with mass production samples for consumer scheduled for release in October 2024 and automotive use in 2025, respectively. To obtain samples, please contact a sales representative or visit the contact page on ROHM’s website. Going forward, we will continue to develop laser light source technology for in-vehicle monitoring and other systems.　　TerminologyVCSEL　　Short for Vertical Cavity Surface Emitting Laser. Although conventionally used for communication, it is increasingly being adopted in recent years as a light source for the optical block in sensing systems.　　DMS　　Stands for Driver Monitoring System. A safe driving assistance function that detects whether the driver can continue safe driving based on facial and eye movements and provides alerts via sounds and/or text to prevent accidents before they occur.　　IMS(ICMS)　　Abbreviation for In-Cabin Monitoring System. This system expands the detection range to include front and rear passenger seats, occupant recognition, and biometric sensing to improve safety and comfort.　　Red Glow　　When high power infrared LEDs are used in sensors and other devices, there is a possibility that wavelengths close to those of visible light will be emitted that can be detected by the human eye. In this case, the sensor appears slightly red, hence the term “red glow”.

Op amps whose main function is to amplify sensor signals for subsequent detection and/or analog-to-digital conversion, is a crucial component in the signal chain - greatly affecting both accuracy and power consumption. ROHM is developing op amps that satisfy the dual need for high accuracy and low current consumption. By further refining the circuit design based on original Nano Energy™ technology, ROHM is now able to offer an op amp that delivers the lowest current consumption on the market.　　The LMR1901YG-M leverages original ultra-low power technology that thoroughly suppresses current increase caused by temperature and voltage changes to reduce current consumption to just 160nA (Typ.) - approximately 38% lower than that of general low power op amps. This not only extends the life of applications powered by internal batteries like electronic shelf labels, but also contributes to longer operating times for smartphones and other devices equipped with rechargeable batteries. At the same time, this low current consumption does not change over the temperature range of -40°C to +105°C - allowing stable low-power operation, even in environments where external temperatures fluctuate, including fire alarms and environmental sensors.　　Other performance enhancements include 45% reduction of input offset voltage to just 0.55mV (Max. Ta=25°C) over general low-current op amps while a maximum input offset voltage temperature drift of 7V/°C is guaranteed. This enabling high accuracy amplification of sensor signals. Capable of operating from 1.7V to 5.5V supply voltage and offering rail-to-rail input/output, LMR1901YG-M is suitable for a wide variety of applications in the industrial equipment and consumer markets. ROHM’s new op amp also complies with the automotive reliability standard AEC-Q100 - ensuring stable operation even under harsh conditions such as vehicle cabins without compromising functionality.　　In addition to various technical documents necessary for circuit design and SPICE models for simulation (available free of charge on ROHM’s website), the LMR1901YG-M can be used with ROHM Solution Simulator to speed up time to market.　　Going forward, ROHM will continue to pursue further power savings in op amps using proprietary ultra-low power technology. On top, ROHM aims to improve the performance of op amp lineups by reducing noise and offset - increasing power savings and expanding the power supply voltage range while contributing to solving social issues through higher accuracy application control.　　Application Examples• Consumer applications: smartphones, smartwatches, wearables, fire alarms, motion sensors, etc.　　• Industrial equipment: electronic shelf labels (ESL), handheld measurement instruments, data loggers, environmental sensors for IoT, etc.　　• Automotive systems: anti-theft sensors, drive recorders, etc.　　Online Sales InformationSales Launch Date: November 2023　　Pricing: $4.0/unit (samples, excluding tax)　　Online Distributors: DigiKey, Mouser and Farnell　　The products will be offered at other online distributors as they become available.。　　Product Information　　Applicable Part No: LMR1901YG-M　　Online Distributors　　What is Nano Energy™ Technology?Nano Energy™ refers to proprietary ultra-low current consumption technology that achieves a current consumption on the order of nano ampere (nA) by combining advanced analog technologies covering circuit design, layout, and processes utilizing ROHM’s vertically integrated production system.　　This contributes to not only extending the operating time of battery operated IoT and mobile devices, but also improved efficiency in industrial and automotive equipment where increased power consumption is problematic.　　*Nano Energy™ is a trademark or registered trademark of ROHM Co., Ltd.　　TerminologyInput Offset Voltage　　Refers to the error voltage that occurs between the input terminals of an op amp.　　Input Offset Voltage Temperature Drift　　The fluctuation in input offset voltage caused by a rise/fall in temperature. The smaller this value is the higher the op amp accuracy. Zero-drift op amps automatically compensate for input offset temperature drift.　　Rail to Rail Input/Output　　A circuit format that allows the input and output voltages of an op amp to accommodate the entire supply voltage range. The supply voltage in this case is called a Rail.　　ROHM Solution Simulator　　A free electronic circuit simulation tool that runs on ROHM’s website. A wide variety of simulations are supported, from component selection and standalone device verification to system-level operational testing.
