OPA2330AIDGKT

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2330AIDGKT is a dual-channel precision operational amplifier manufactured by Texas Instruments, featuring CMOS zero-drift architecture. It operates within a supply voltage range of 1.8 V to 5.5 V and delivers a gain-bandwidth product of 350 kHz with a slew rate of 160 mV/us. Key electrical specifications include an input offset voltage of 8 µV, input bias current of 200 pA, and quiescent current of 21 µA per channel. The device supports rail-to-rail input and output, offers a common-mode rejection ratio of 115 dB, and functions reliably across an extended temperature range from -40°C to +125°C in an 8-VSSOP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'A' indicates the enhanced precision grade compared to standard variants. Confirm the 'DGKT' suffix corresponds to the 8-VSSOP package with tape-and-reel packaging. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference the datasheet revision history for any recent marking or assembly changes.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low offset voltage stability is critical without requiring chopper stabilization artifacts. Compare against the OPA2333 for lower offset requirements or the OPA330 for single-channel needs. Consider the 350 kHz bandwidth limit for high-speed applications. Evaluate the 8-VSSOP footprint constraints against available PCB real estate.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPAx330 family of zero-drift amplifiers, designed to replace traditional chopper-stabilized op amps with lower noise and simpler implementation. It shares architectural similarities with the OPA2333 but features slightly higher offset voltage specifications. The series targets high-accuracy DC measurement applications where long-term stability is paramount.
