  RS299系列是一款支持高工作电压、宽共模输入电压范围的集成电流检测芯片,工作电压支持4.5V至76V,共模输入电压范围亦支持4.5V至76V;可以很好应对24V、48V母线电压系统的电流采集应用。

  RS299系列提供20、50、60、100四种固定增益,增益误差低至0.25%,以使其能满足更多的应用场景和电流采集精度。

  其他主要参数特性如下:

  Ø 增益带宽(GBP):135KHz;

  Ø 低输入失调电压(Vos):100μV;

  Ø 低输入偏置电流(IB):9.5μA;

  Ø 低功耗(Iq):135μA;

  Ø 高电源纹波抑制比(PSRR):130dB

  Ø 高共模抑制比(CMRR):130dB

  Ø 容性负载能力;500pF

  Ø 扩展级工业温度范围:-40°C ~ 125°C。
