Description

The LMP™8272, LMP8277 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 LMP8272, LMP8277 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 14 and is adequate to drive an ADC to full scale in most cases. This fixed gain is achieved in two separate stages, a pre-amplifier with gain of +7 and a second stage amplifier with a gain of +2. The internal signal path between these two stages is brought out on two pins that provide a connection for a filter network.

The LMP8272, LMP8277 will function with reduced specifications over the extended common mode input voltage range of -5 to 36 Volts. This feature makes the device suitable for applications with load dump in automotive systems.
