Overview
The OPA2209AIDR is a dual, precision operational amplifier from Texas Instruments, part of the OPA209 series. It is renowned 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. This amplifier is designed to offer high precision and low noise, making it suitable for a wide range of applications that require fast settling times and high accuracy. The OPA2209AIDR is available in an 8-pin SOIC package and 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.
