NCS2211MNTXG

Overview

The NCS2211MNTXG is a high-performance, low-distortion Class-AB audio power amplifier manufactured by onsemi. It features a differential output and shutdown mode for efficient power management. The device is designed to deliver 1W of output power into an 8Ω bridge-tied load (BTL). It operates within a wide voltage range of 2.7V to 5.5V and functions reliably across an extended temperature range up to +85°C. Packaged in an 8-pin DFN measuring 3x3x0.95mm, it offers a typical gain bandwidth product of 12MHz.
