Overview
The NCV2211DR2G, produced by onsemi, is a high-performance, low-distortion Class A/B audio amplifier. This device is designed to deliver high-quality audio output, making it suitable for a variety of applications. It can operate over a wide temperature range of -40°C to +85°C and is optimized for single-supply voltage operation, which is particularly beneficial for portable applications. The amplifier features a shutdown/enable function to extend battery life by reducing the quiescent current to a maximum of 1 µA.
