2.2nV/rtHz, 18MHz, Precision, RRO, 36V Operational Amplifier - OPA2209

OPA2209 (ACTIVE)

2.2nV/rtHz, 18MHz, Precision, RRO, 36V Operational Amplifier

 

Description

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. The dual OPA2209 comes in both MSOP-8 and SO-8 packages. The quad OPA4209 is available in the TSSOP-14 package.

The OPA209 series is specified from –40°C to +125°C.
