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.

SBOS377A – OCTOBER 2006 – REVISED FEBRUARY 2007
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported. Short-circuit to ground, one amplifier per package.
