INA191

采用 WCSP 封装、具有皮安级 IB 和使能引脚的 40V、双向、超精密电流感应放大器

INA191 是一款低功耗、电压输出、电流分流监控器（也称为电流检测放大器），常用于过流保护和精密电流测量（用于实现系统优化），此外它还可用于闭环反馈电路中。该器件可在独立于电源电压之外的 –0.2V 至 +40V 共模电压下检测分流器上的压降。INA191 的低输入偏置电流允许使用更大的电流检测电阻器，从而能够提供微安级的精确电流测量。提供了五个固定增益：25V/V、50V/V、100V/V、200V/V 或 500V/V。零漂移架构的低失调电压扩展了电流测量的动态范围，并允许使用具有更低功率损耗的更小检测电阻器，同时仍提供精确的电流测量。\n\nINA191 由 1.7V 至 5.5V 单 • 低功耗： \n• 低关断电流：100nA（最大值）\n• 低输入偏置电流：100pA（典型值）（支持微安级电流测量）\n• ±0.25% 的最大增益误差（A2 至 A5 器件）\n• ±12µV（最大值）的失调电压\n• 宽共模电压范围：–0.2V 至 +40V\n• INA191A1：25V/V\n• INA191A3：100V/V\n• INA191A5：500V/V\n• 封装：0.895mm2 DSBGA;
