LMP8640 Overview
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 mon mode voltages with a supply voltage range from 2.7 V to 12 V. The LMP8640 and LMP8640-Q1 accept input signals with mon mode voltage range from -2 V to 42 V, while the LMP8640HV accepts input signal with mon mode voltage range from -2 V to...
