  RSA4080系列提供20、50、60、100四种固定增益,增益误差低至0.5%,以使其能满足更多的应用场景和电流采集精度。与RSA4081相比,区别仅仅在于没有基准电压输入脚,其他主要参数特性如下:

  Ø 增益带宽(GBP):180KHz;

  Ø 低输入失调电压(Vos):100μV;

  Ø 低输入偏置电流(IB):4μA;

  Ø 低功耗(Iq):150μA(Full Tem. MAX);

  Ø 高电源纹波抑制比(PSRR):135dB

  Ø 高共模抑制比(CMRR):140dB

  Ø 容性负载能力;500pF

  Ø 扩展级工业温度范围:-40°C ~ 125°C。
