OPA354AIDDAG3

Instrumentation, Op Amps, Buffer Amps Overview

The OPA354AIDDAG3 is a single-channel, high-speed voltage feedback operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 100 MHz and a slew rate of 150 V/us. The device operates within a supply voltage range of 2.5 V to 5.5 V with a typical quiescent current of 4.9 mA. Key electrical parameters include an input offset voltage of 2 mV, input bias current of 50 pA, and output current capability of 100 mA per channel. It provides rail-to-rail input and output capabilities, low input voltage noise density of 6.5 nV/sqrt Hz, and high open-loop voltage gain of 110 dB. The component is housed in an 8-SOIC package and supports operation temperatures from -40°C to +125°C.
