LMP8640 Datasheet (Texas Instruments) - Precision High Voltage Current Sense Amplifier

LMP8640, Precision High Voltage Current Sense Amplifier

The LMP8640, LMP8640-Q1 and the LMP8640HV are precision current sense amplifiers that detect small differential voltages across a sense resistor in the presence of high input common mode voltages with a supply voltage range from 2.7 V to 12 V.

The LMP8640 and LMP8640-Q1 accept input signals with com
