LMC8101MM

Instrumentation, Op Amps, Buffer Amps Overview

The LMC8101MM is a single-channel, rail-to-rail input and output CMOS operational amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.7V to 10V and features a shutdown function that reduces supply current to 1µA maximum. The device is housed in an 8-pin VSSOP package with dimensions of 3.0mm x 4.9mm. Key electrical specifications include a gain-bandwidth product of 1MHz, a slew rate of 1V/µs, and an input offset voltage of ±5mV maximum. It provides an output short circuit current of 10mA and maintains operation across a temperature range of -40°C to +85°C.
