LMP8481 Overview
The LMP8480 and LMP8481 are precision high-side current sense amplifiers that amplify a small differential voltage developed across a current sense resistor in the presence of high input mon-mode voltages. These amplifiers are designed for bidirectional (LMP8481) or unidirectional (LMP8480) current applications and accept input signals with mon-mode voltage range from 4 V to 76 V with a bandwidth of 270 kHz.
