TS271IN

Instrumentation, Op Amps, Buffer Amps Overview

The TS271IN is a single operational amplifier manufactured by STMicroelectronics, utilizing silicon gate CMOS technology. It operates on single or dual supplies ranging from 3V to 16V. The device features an externally programmable ISET current via a resistor between pins 8 and 4, allowing selection of 1.5µA, 25µA, or 130µA to optimize the consumption-speed ratio. Key electrical parameters include a gain bandwidth product up to 2.3 MHz, a slew rate up to 4.5 V/µs, and input bias currents as low as 1 pA. It offers offset null capability and output voltage swing to ground.
