Working Principles

The NAU8223YG is a stereo audio amplifier that operates by amplifying low-power audio signals from the input channels (INL and INR) using an internal boost converter. The amplified audio signals are then output through the left and right channel outputs (OUTL and OUTR). The amplifier can be controlled using the shutdown control input (SD), allowing for power-saving operation when not in use.

Detailed Application Field Plans

The NAU8223YG is suitable for various applications, including but not limited to: - Portable audio devices - Mobile phones - Tablets - Bluetooth speakers - Gaming consoles - Personal computers
