Overview
The OPA237NA/3K is a single-supply operational amplifier from Texas Instruments' MicroAmplifier series. This device is known for its miniature size, low offset voltage, low quiescent current, and wide supply range, making it ideal for single-supply, battery-operated, and space-limited applications. The OPA237 series includes single, dual, and quad versions, although the quad version is currently obsolete. These amplifiers are designed to operate from either single or dual supplies, offering flexibility in various design scenarios.
