The LMP7701MF is a RRIO Precision Amplifier with a CMOS input stage and a wide supply voltage range. The specified low offset voltage of less than ±200µV along with the specified low input bias current of less than ±1pA make the LMP7701 ideal for precision applications. The amplifier 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 the amplifier is great choices in many applications where conventional CMOS parts cannot operate under the desired voltage conditions. The amplifier has a rail-to-rail input stage that significantly reduces the CMRR glitch commonly associated with it. 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 amplifier swings within 40mV of either rail to maximize the signal dynamic range in applications requiring low supply voltage.
