LMP8270, LMP8275 High Common Mode, Gain of 20, Precision Voltage Difference Amplifiers
General Description
The LMP™8270, LMP8275 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 LMP8270, LMP8275 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. The LMP8270, LMP8275 have a preamplifier with a fixed gain of 10 and an amplifier with a fixed gain of 2, achieving overall fixed gain of 20.
