INA21x为电压输出,分流监控器(也称作电流感测放大器)。该器件通常可针对系统优化提供过流保护和精密电流测量,还常用于闭环反馈电路。该系列器件可感测分流电阻在-0.3V至26V共模电压范围内的压降,与电源电压无关。共有6种固定增益可供选用:50V /V, 75V /V,100V /V,200V /V,500V /V或1000V /V.该系列器件采用零漂移架构,偏移较低,因此在进行电流感测能能够分流电阻两端的最大压降保持在10mV满量程以下。
该系列器件可由电压为2.7V至26V的单电源供电,最大电源流耗为100μA。所有器件版本均在-40°C至+ 125°C的扩展运行温度范围内
额定运行,采用SC70和UQFN封装。
