The BA5210FS is a power amplifier with a built-in monaural speaker / stereo headphone switch. The speaker drive is BTL for large output, and when the headphones are connected, the "center-amp" design means that coupling is not required. This significantly reduces the number of external components required, and makes this IC ideal for compact sets that have high component density. Mute and standby functions are provided, and direct microprocessor control is possible. FApplications
