3 Description

The OPA2210 is the next generation of the OPA2209 operational amplifier. The OPA2210 precision op amp is built on TI's precision super-beta complementary bipolar semiconductor process, which provides ultra-low flicker noise, low offset voltage, and low offset voltage drift over temperature.

The OPA2210 achieves very low voltage noise density (2.2nV/√Hz) while consuming only 2.5mA (max) per amplifier. The device also provides rail-to-rail output swing, which helps maximize dynamic range.

In precision data acquisition applications, the OPA2210 achieves fast settling times with 16-bit accuracy, even for a 10V output swing. Excellent ac performance with only 35μV (max) offset and 0.6μV/°C (max) temperature drift make the OPA2210 ideal for high-speed, high-precision applications.

The OPA2210 operates 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 is specified over a –40°C to 125°C operating temperature range.

The OPA2210 is available in 8-lead SOIC, VSSOP and WSON packages.
