OPA4340EA/250

Instrumentation, Op Amps, Buffer Amps Overview

The OPA4340EA/250 is a quad microPOWER CMOS operational amplifier manufactured by Texas Instruments. It features rail-to-rail input and output capabilities, supporting single-supply operation from 2.5 V to 5.5 V. Key electrical parameters include a gain-bandwidth product of 5.5 MHz, a slew rate of 6 V/µs, and an input offset voltage of 150 µV. The device draws 750 µA of supply current across all four channels and provides 50 mA of output drive per channel. It operates within a temperature range of -40°C to 85°C and is housed in a 16-SSOP package.
