OPA4209 2.2nV/rtHz、18MHz、36V RRO 精密运算放大器

The OPA209 series of precision operational amplifiers achieve very low voltage noise density (2.2nV/√Hz) with a supply current of only 2.5mA (max). 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 10V output swings. This excellent ac performance, combined with only 150µV (max) 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 to ±18V, or single-supply operation from +4.5V to +36V.

The OPA209 is available in the SOT23-5, MSOP-8 and the standard SO-8 packages
