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.

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.
