The OPA2211 is a precision operational amplifier that achieves very low 1.1 nV/√Hz noise density with a supply current of only 3.6 mA. This device also offers rail-to-rail output swing, which maximizes dynamic range.

The extremely low voltage and low current noise, high speed, and wide output swing of the OPA2211 make this device an excellent choice as a loop filter amplifier in PLL applications.

In precision data acquisition applications, the OPA2211 provides 700-ns settling time to 16-bit accuracy throughout 10-V output swings. This ac performance, combined with only 240-µV of offset and 0.35-µV/°C of drift over temperature, makes the OPA2211 ideal for driving high-precision 16-bit analog-to-digital converters (ADCs) or buffering the output of high-resolution digital-to-analog converters (DACs).

The OPA2211 is specified over a wide dual-power supply range of ±2.25 V to ±18 V, or for single-supply operation from 4.5 V to 36 V.

This op amp is specified from TJ = –55°C to 150°C.
