1. Introduction
The Texas Instruments LMP8480/81 evaluation module (EVM) helps designers quickly evaluate the
operation and performance of the LMP8480/81 76V Precision High Side Current Sense Amplifiers. The EVM
is ready to connect to power, load, and test instruments through the use of on-board terminals.

The EVM contains one LMP8480 or LMP8481 high side evaluation circuit. The EVM’s come pre-assembled
with the LMP8480/81 device, 0.1Ω sense resistor; bypass capacitor and connection terminals installed. The
Bi-Directional EVM’s include the JP1 and JP2 reference jumpers and terminals.
