LMV982IDGSRG4

Instrumentation, Op Amps, Buffer Amps Overview

The LMV982IDGSRG4 is a dual low-voltage operational amplifier from Texas Instruments, characterized by rail-to-rail input and output capabilities. It operates within a supply voltage range of 1.8 V to 5 V and features a shutdown mode for power conservation. Key electrical specifications include a gain bandwidth product of 1.4 MHz at 1.8 V and 1.5 MHz at 5 V, with a typical quiescent current of 103 µA per channel at 1.8 V. The device supports an operating temperature range from -40°C to +125°C and is housed in a 10-pin MSOP package.
