LMC6442IMX

Instrumentation, Op Amps, Buffer Amps Overview

The LMC6442IMX is a dual micropower operational amplifier featuring rail-to-rail output swing, designed for single-supply operation between 1.8V and 11V. It offers a typical supply current of 0.95 µA per amplifier and a gain-bandwidth product ranging from 9.5 kHz to 10.5 kHz depending on voltage. The device provides high voltage gain up to 103 dB and low input bias current of 5 fA typical. It is housed in an 8-lead SOIC surface-mount package.
