Overview
The OPA4209AIPW from Texas Instruments is a precision operational amplifier that belongs to the OPA209 series. This quad-channel amplifier is known for its low voltage noise density of 2.2 nV/√Hz at 1 kHz and a low quiescent current of 2.5 mA per channel. It is designed for high-precision, low-power applications and offers a wide supply range from ±2.25 V to ±18 V or single-supply operation from 4.5 V to 36 V. The OPA4209AIPW is packaged in a 14-pin TSSOP, making it suitable for a variety of applications requiring multiple channels of high-performance amplification.
