Product Summary

The LMP7731MFX/NOPB is a single, low offset voltage, rail-to-rail input and output precision amplifier with a CMOS input stage and a wide supply voltage range. It is part of the LMP. precision amplifier family and is ideal for sensor interface and other instrumentation applications. The LMP7731MFX/NOPB is built utilizing VIP50 technology, which allows the combination of a CMOS input stage and a 12V common mode and supply voltage range. This makes it a great choice in many applications where conventional CMOS parts cannot operate under the desired voltage conditions. The LMP7731MFX/NOPB has a rail-to-rail input stage that significantly reduces the CMRR glitch commonly associated with rail-torail input amplifiers. This is achieved by trimming both sides of the complimentary input stage, thereby reducing the difference between the NMOS and PMOS offsets. The output of the LMP7731MFX/NOPB swings within 40 mV of either rail to maximize the signal dynamic range in applications requiring low supply voltage. It is offered in space saving SOT23-5.
