INA199B2QDCKRQ1
The INA199-Q1 is an AEC-Q100 qualified, bidirectional current-sense amplifier that measures voltage across a shunt resistor on either the high or low side. It offers fixed gains of 50, 100 or 200 V/V, a maximum input offset of 150uV, a common-mode range of -0.3V to 26V, and a bandwidth up to 80kHz. The B2 version provides a gain of 100 V/V and operates from -40C to 125C.
