The OPA211 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 OPA211 series make these devices an excellent choice as a loop filter amplifier in PLL applications.
In precision data acquisition applications, the OPA211 series of op amps 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 OPA211 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 OPA211 series 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 series of op amps is specified from TA = –55°C to 210°C.
