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.
