3 Description
The OPA209 series of precision operational
amplifiers achieve very low voltage noise density
(2.2 nV/√Hz) with a supply current of only 2.5 mA
(maximum). This series also offers rail-to-rail output
swing, which helps to maximize dynamic range.
In precision data acquisition applications, the
OPA209 provides fast settling time to 16-bit accuracy,
even for 10-V output swings. This excellent ac
performance, combined with only 150 μV (maximum)
of offset and low drift over temperature, makes the
OPA209 very suitable for fast, high-precision
applications.
The OPA209 is specified over a wide dual powersupply
range of ±2.25 V to ±18 V, or single-supply
operation from 4.5 V to 36 V.
The OPA209 is available in the 5-pin SOT-23, 8-pin
VSSOP, and the standard 8-pin SOIC packages. The
dual OPA2209 comes in both 8-pin VSSOP and 8-pin
SOIC packages. The quad OPA4209 is available in
the 14-pin TSSOP package.
The OPA209 series is specified from –40°C to 125°C.
