OPA330AIDCKTG4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA330AIDCKTG4 is a precision, zero-drift CMOS operational amplifier manufactured by Texas Instruments. It features a single channel with rail-to-rail input and output capabilities. Key electrical parameters include a gain-bandwidth product of 350 kHz, a slew rate of 160 mV/us, and an input offset voltage of 8 uV. The device operates on supply voltages ranging from 1.8 V to 5.5 V with a typical quiescent current of 21 uA per channel. It provides an output current of 5 mA and exhibits a common-mode rejection ratio of 115 dB. The input voltage noise density is 55 nV/sqrt Hz, and the input bias current is 200 pA. It is housed in a SC-70-5 package and functions within a temperature range of -40 C to +125 C.
