Product Overview
The OPA2333 is a Texas Instruments dual zero-drift CMOS operational amplifier for Signal_Chain designs that require two amplifier channels in one package. Its recommended supply range is 1.8 V to 5.5 V, with a specified temperature range of -40°C to 125°C and electrical-characteristics operating range extending to 150°C.
For precision signal conditioning, the device is specified with 2 µV typical and 10 µV maximum input offset voltage at VS = 5 V and TA = 25°C. Offset drift is 0.02 µV/°C typical and 0.05 µV/°C maximum across -40°C to 125°C. The input common-mode range extends from (V-) - 0.1 V to (V+) + 0.1 V, with 106 dB minimum and 130 dB typical common-mode rejection ratio.
Package options include VSON-8, SOIC-8, and VSSOP-8. Thermal data covers SOIC, VSSOP, and VSON variants, including 46.7°C/W junction-to-ambient thermal resistance for the VSON package. The device also provides 350 kHz gain-bandwidth product, 0.16 V/µs slew rate, near-rail output swing, and low quiescent current for low-voltage dual-op-amp circuits.
