Description:

The OPA210 and OPA2210 (OPAx210) are the next-generation products of the OPAx209 operational amplifier family. Built on TI's precision super-β complementary bipolar semiconductor process, the OPAx210 precision operational amplifiers deliver ultra-low flicker noise, low offset voltage, and low offset voltage drift. The OPAx210 achieves a very low voltage noise density of 2.2 nV/√Hz while consuming only 2.5 mA (maximum) of current per amplifier. These devices also offer rail-to-rail output swing to help maximize dynamic range. In precision data acquisition applications, the OPAx210 enables fast settling time to 16-bit accuracy, even with a 10V output swing. Excellent AC performance, combined with an offset voltage of only 35 µV (maximum) and a drift of 0.6 µV/°C (maximum), makes the OPAx210 ideal for high-speed, high-precision applications. The OPAx210 operates across a wide dual-supply voltage range of ±2.25V to ±18V or a single-supply range of 4.5V to 36V, with a rated operating temperature range of –40°C to +125°C.
