Description：

The OPA209 series of precision operationalamplifiers 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 outputswing, which helps to maximize dynamic range.In precision data acquisition applications, theOPA209 provides fast settling time to 16-bit accuracy,even for 10-V output swings. This excellent acperformance, combined with only 150 µV (maximum)of offset and low drift over temperature, makes theOPA209 very suitable for fast, high-precisionapplications.The OPA209 is specified over a wide dual powersupply range of ±2.25 V to ±18 V, or single-supplyoperation from 4.5 V to 36 V.The OPA209 is available in the 5-pin SOT-23, 8-pinVSSOP, and the standard 8-pin SOIC packages. Thedual OPA2209 comes in both 8-pin VSSOP and 8-pinSOIC packages. The quad OPA4209 is available inthe 14-pin TSSOP package.The OPA209 series is specified from –40°C to 125°C.
