OPA4209数据手册TI中文资料规格书

描述 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 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.
