The is a quad wide supply range precision Operational Amplifier with CMOS input, rail-to-rail input and output. The LMP770x is part of the LMP™ precision amplifier family and is ideal for sensor interface and other instrumentation applications. The specified low-offset voltage of less than ±200µV, along with the specified low input bias current of less than ±1pA. The LMP770x is built using VIP50 technology, which allows the combination of a CMOS input stage and a 12V common-mode and supply voltage range. This makes the LMP770x ideal for applications where conventional CMOS parts cannot operate under the desired voltage conditions. The LMP770x each have a rail-to-rail input stage that significantly reduces the CMRR glitch commonly associated with rail-to-rail input amplifier. This is achieved by trimming both sides of the complimentary input stage, thereby reducing the difference between the NMOS and PMOS offsets.
