Overview
The OPA4209AIPWR is a quad-channel precision operational amplifier produced by Texas Instruments. This device 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 OPA4209AIPWR features rail-to-rail output swing, which maximizes dynamic range, and is suitable for fast, high-precision applications. It operates 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, making it versatile for various applications.
