LMP8271, LMP8276 High Common Mode, Gain of 20, Bidirectional Precision
Voltage Difference
Amplifiers
General Description
The LMP™8271, LMP8276 are fixed gain differential
amplifiers with a -2V to 27V input common mode
voltage range and a supply
voltage range of 4.
5V to 5.
5V.
The LMP8271, LMP8276 are precision
amplifiers 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 p...
