LMP8602 60V Common Mode Fixed Gain Bidirectional Precision Current Sensing Amplifier

RS Components Part # 761-6330
Supplied in sealed RS package

Manufactured by Texas Instruments - 8pin MSOP SMD package

General Description

The LMP8602 is a fixed gain precision amplifier. The parts will amplify and filter small differential signals in the presence of high common mode voltages. The input common mode voltage range is –22V to +60V when operating from a single 5V supply. With a 3.3V supply, the input common mode voltage range is from –4V to +27V. The LMP8602 and LMP8603 are members of the Linear Monolithic 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 are 100% tested and all bold values are also 100% tested over temperature.
