OPA2210 - 2.2-nV/√Hz, Low-Power, 36-V Operational Amplifier

The OPA2210 is the next generation of OPA2209 operational amplifier (op amp). The OPA2210precision operational amplifier is built on TI’s precision super-ß complementary bipolarsemiconductor process, which offers ultra-low flicker noise, low offset voltage, and low offsetvoltage temperature drift.

The OPA2210 achieves very low voltage noise density (2.2 nV/√Hz)while consuming only 2.5 mA (maximum). This device also offers rail-to-rail output swing, whichhelps to maximize dynamic range.

In precision data acquisition applications, the OPA2210 provides fast settling time to16-bit accuracy, even for 10-V output swings. Excellent ac performance, combined with only 50 µV(maximum) of offset and 0.5 µV/°C (maximum) drift over temperature, makes the OPA2210 very suitablefor high-speed, high-precision applications.

The OPA2210 is specified over a wide dual power-supply range of ±2.25 V to ±18 V, orsingle-supply operation from 4.5 V to 36 V and is specified from –40°C to 125°C.

The OPA2210 comes in the 8-pin VSSOP package.
