LMP8271 High Common Mode, Gain of 20, Bidirectional Precision Voltage Difference Amplifier
General Description
The LMP8271 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 LMP8271 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 drive an ADC to full scale in most cases. This fixed gain is achieved in two separate stages, a preamplifier with gain of +10 and a second stage amplifier with a gain of +2. The internal signal path is brought out on two pins that provide a connection for a filter network. The LMP8271 will function over an extended common mode input voltage range making the device suitable for applications with load dump events such as a
