25V to ±18V, +4.
5V to +36V RAIL-TO-RAIL OUTPUT OUTPUT CURRENT: 30mA SHUTDOWN: 20µA (max) AVAILABLE IN TINY DFN-8 (3x3mm), MSOP-8, SO-8 DESCRIPTION The OPA211 series achieves very low 1.
1nV/√Hz noise density with a supply current of only 3.
6mA.
It also offers rail-to-rail output swing, which helps to maximize dynamic range.
The OPA211 series’ extremely low voltage and current noise, high speed and wide output swing make it an excellent choice as a loop filter amplifier in PLL applications.
In precision data acquisition applications, the OPA211 series of op amps provide <1µs settling time to 16-bit accuracy even for 10V output swings.
This ac performance, combined with only 100µV of offset and low drift over temperature, make the OPA211 highly suitable for driving fast, high-precision analog-to-digital converters (ADCs) or buffering the outputs of high-resolution digital-to-analog converters (DACs).
The OPA211 is specified over the very wide dual-power supply range of ±2.
25V to ±18V, or single-supply operation from +4.
5V to +36V.
The OPA211 is available in the tiny DFN-8 (3×3mm) and MSOP-8 and SO-8 packages.
A dual version, the OPA2211, is available in the DFN-8 (3×3mm) or an MSOP-8 package.
This series of op amps is specified from –40°C to +125°C.
