Product Overview
The OPA333 is a Texas Instruments zero-drift CMOS operational amplifier in the Signal_Chain category. It is specified as a single operational amplifier, with input offset voltage of 2 µV typical and 10 µV maximum at VS=5 V and TA=25°C. Across -40°C to 125°C, offset drift is specified at 0.02 µV/°C typical and 0.05 µV/°C maximum, supporting low-drift signal conditioning applications.
The device operates from a recommended 1.8 V to 5.5 V supply range, with an absolute maximum supply rating of 7 V. Quiescent current per amplifier is 17 µA typical and 25 µA maximum at TA=25°C, or 28 µA maximum across -40°C to 125°C. AC and output parameters include 350 kHz typical gain-bandwidth product, 0.16 V/µs typical slew rate, and 30 mV typical output swing from rail with a 10 kΩ load at TA=25°C.
Package and assembly options include SOT-23(5), SOT/SC70(5), SOIC(8), VSON(8), and VSSOP(8). The extracted pin functions define +IN, -IN, OUT, V+, and V- positions for SOIC, SOT, and SC70 packages, while thermal resistance junction-to-ambient is specified for SOIC, SOT, and SC70 variants.
