3 Description
The OPAx211 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 OPAx211
series make these devices an excellent choice as a
loop filter amplifier in PLL applications.
In precision data acquisition applications, the
OPAx211 series of operational amplifiers provides
700-ns settling time to 16-bit accuracy throughout 10-
V output swings. This ac performance, combined with
only 125 μV of offset and 0.35 μV/°C of drift over
temperature, makes the OPAx211 series suitable for
driving high-precision 16-bit analog-to-digital
converters (ADCs) or buffering the output of high-
resolution digital-to-analog converters (DACs).
The OPAx211 series is specified over a wide dual-
power supply range of ±2.25 to ±18 V, or for single-
supply operation from 4.5 to 36 V.
The OPA211 is available in the small SON-8 (3 mm ×
3 mm), VSSOP-8, and SOIC-8 packages. A dual
version (OPA2211) is available in a SON-8 (3 mm × 3
mm) or an SO-8 PowerPAD™ package. This series
of operational amplifiers is specified from TA = –40°C
to +125°C.
