Precision dual op-amp for low-drift signal chains
The Texas Instruments OPA2334AIDGST is a dual zero-drift operational amplifier from the Zero-Drift series, delivering a 1 µV input offset voltage and 2 MHz gain-bandwidth product in a 10-VSSOP package. Rail-to-rail output swing and a 2.7 V to 5.5 V supply range make it a fit for single-supply precision circuits — thermocouple amplifiers, load-cell bridges, and current-sense front-ends where offset drift over temperature would otherwise swamp the signal. The 285 µA supply current per two channels keeps the power budget tight for loop-powered or battery-operated instruments.
1 µV offset — what it means for the BOM
A 1 µV typical input offset is the reason you pick this part over a general-purpose op-amp. The zero-drift topology keeps that offset from walking with temperature, so the design avoids a trim pot or a software calibration routine.
Active, no LTB risk
The OPA2334AIDGST carries an Active product status and is ROHS3 compliant. No last-time-buy window is open, no end-of-life notice is pending.
Package and temperature grade
The 10-VSSOP package (3.00 mm width, 0.118" body) is a surface-mount footprint suited for compact PCBs in industrial or automotive sensor modules. The -40°C to 125°C operating range covers engine-bay, outdoor telecom, and factory-floor environments without derating.
