Overview
The OPA2209AIDGKT is a dual-channel precision operational amplifier produced by Texas Instruments. This component is part of the OPA209 series, known for its very low voltage noise density of 2.2 nV/√Hz at 1 kHz and a low quiescent current of 2.5 mA per channel. The OPA2209AIDGKT is housed in an 8-pin VSSOP (DGK) package and operates over a wide supply range from ±2.25 V to ±18 V or from 4.5 V to 36 V in single-supply configurations. It features rail-to-rail output swing, which maximizes dynamic range, making it highly suitable for fast, high-precision applications such as precision data acquisition, low-noise signal processing, and high-performance ADC and DAC drivers.
