OPA210IDR

The OPAx210 precision operational amplifiers are built on a precision super ß complementary bipolar semiconductor process, offering ultra-low flicker noise, low offset voltage, and low offset voltage drift. The OPAx210 can achieve a very low voltage noise density (2.2nV/√Hz) while each amplifier only consumes 2.5mA (max) of current. Both devices also provide rail-to-rail output swing, which helps to maximize the dynamic range. In precision data acquisition applications, the OPAx210 can achieve a fast settling time with 16-bit accuracy, even for a 10V output swing. The excellent AC performance, an offset voltage of only 35μV (max), and a drift of 0.6μV/°C (max) make the OPAx210 well-suited for high-speed, high-precision applications. The OPAx210 can operate over a wide dual-supply voltage range of ±2.25V to ±18V or a wide single-supply voltage range of 4.5V to 36V, and has a specified operating temperature range of –40°C to +125°C.
