The OPA210 and OPA2210 ( OPAx210) are the next generation of OPAx209 operational amplifier (op amp). The OPAx210 precision op amps are built on TI’s precision, super-beta, complementary bipolar semiconductor process, which offers ultra-low flicker noise, low offset voltage, and low offset voltage temperature drift.

The OPAx210 achieve very low voltage noise density (2.2 nV/√Hz) while consuming only 2.5 mA (maximum) per amplifier. These devices also offer rail-to-rail output swing, which helps maximize dynamic range.

In precision data-acquisition applications, the OPAx210 provide fast settling time to 16-bit accuracy, even for 10-V output swings. Excellent ac performance, combined with only 35 µV (maximum) of offset and 0.6 µV/°C (maximum) drift over temperature, makes the OPAx210 an excellent choice for high-speed, high-precision applications.

The OPAx210 are specified over a wide dual power-supply range of ±2.25 V to ±18 V, or single-supply operation from 4.5 V to 36 V, are specified from –40°C to +125°C.
