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,
The OPA209 is specified over a wide dual power-supply 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.
