LMP8275 - Texas Instruments

LMP8275 Precision Voltage Difference Amplifier

The LMP8275 is a fixed gain differential amplifier with a −2V to 16V input common mode voltage range and a supply voltage range of 4.75V to 5.5V. The LMP8275 is part of the LMP™ precision amplifier family which will detect, amplify and filter small differential signals in the presence of high common mode voltages. The gain is fixed at 20 and is adequate to d.
