BA5210FS

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 re-

quired. 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 pos-

sible.

FApplications

Notebook computers, electronic books, portable CD

players, video cameras with built-in monitors, LCD TVs,

radios, and electronic instruments

FFeatures

1) Built-in BTL / stereo switch circuit.

2) Mute function.

3) Standby function.

4) Few external components required.

5) Low current dissipation and good sound quality.
