AN-1940 LMP8601 Evaluation Board
1 Introduction
The LMP8601 current sense evaluation board is designed to evaluate the LMP8601, 60 V common mode,
bidirectional precision current sensing amplifier. This board has a LMP8601 part mounted on the printed
circuit board (PCB) together with the required de-coupling capacitor, power supply connections, input and
output (I/O) connectors and a 3-pin header for connecting the offset pin to either GND or V
S

2 General Description
The LMP8601 and LMP8601Q are fixed 20x gain precision amplifiers. The part amplifies and filters small
differential signals in the presence of high common mode voltages. The input common mode voltage
range is −22 V to +60 V when operating from a single 5 V supply. With 3.3 V supply, the input common
mode voltage range is from −4 V to +27 V. The LMP8601 and LMP8601Q are members of the Linear
Monolitic Precision ( LMP™) family and are ideal parts for unidirectional and bidirectional current sensing
applications. All parameter values of the parts that are shown in the tables of the LMP8601, LMP8601-Q1
60-V Common-Mode Bidirectional Precision Current Sensing Amplifier Data Sheet (SNOSAR2) are 100%
tested and all bold values are also 100% tested over temperature.
