Product Summary

The LMP8270MA 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 LMP8270MA 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 gain is achieved in two stages, a preamplifier with a fixed gain of 10 and a second stage amplifier with a fixed gain of 2. The internal signal path between these two stages is brought out on two pins, A1 and A2, which provide a connection for a filter network. The LMP8270MA is ideal for: (1)Fuel injection control; (2)High and low side driver configuration current sensing; (3)Power management systems.
