The AS2376Q is a low noise (9.5nV/√Hz), low offset (25μV, maximum), operational amplifier that is precision optimized by using post-package trim. With a 5.5MHz bandwidth, the device is suitable for a wide array of filtering and control applications. The low voltage operation, low quiescent current of 950μA (maximum), and excellent PSRR makes the AS2376Q suitable for direct battery-powered applications and noise-sensitive applications with noisy low-voltage rails.

The dual AS2376Q is offered in the SO-8 (Standard) package, specified for operation from -40°C to +125°C. The device is qualified to AEC-Q100 Grade 1 with automotive-grade supporting PPAPs.
