3 Description
The OPA2211-EP 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 OPA2211-
EP series make these devices an excellent choice as
a loop filter amplifier in PLL applications.
In precision data acquisition applications, the
OPA2211-EP 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 OPA2211-EP
ideal for driving high-precision 16-bit analog-to-digital
converters (ADCs) or buffering the output of high-
resolution digital-to-analog converters (DACs).
The OPA2211-EP is specified over a wide dual-power
supply range of ±2.25 V to ±18 V, or for single-supply
operation from 4.5 to 36 V.
The OPA2211-EP is available in a small DFN-8 (3-
mm × 3-mm) package. These operational amplifiers
are specified from T_J = –55°C to 125°C.
