The OPA2211-EP series of precision operational amplifiers achieves very-low 1.1-nV/√Hz noise density with a supply current of only 3.6 mA. This series 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-EP series make these devices an excellent choice as a loop filter amplifier in PLL applications.

In precision data acquisition applications, the OPA2211-EP series of operational amplifiers provides 700-ns settling time to 16-bit accuracy throughout 10-V output swings. This AC performance, combined with only 125 µV of offset and 0.35 µV/°C of drift over temperature, makes the OPA2211-EP 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-EP is specified over a wide dual-power supply range of ±2.25 V to ±18 V, or for single-supply operation from 4.5 to 36 V.

The OPA2211-EP is available in a small DFN-8 (3-mm × 3-mm) package. These operational amplifiers are specified from TJ = -55°C to 125°C.
