BA5210FS

Audio ICs Speaker / headphone switch power amplifier 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 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 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. FBlock diagram 4) Few external components required. 5) Low current dissipation and good sound quality. 510 Audio ICs FAbsolute maximum ratings (Ta = 25_C) BA5210FS FRecommended operating conditions (Ta = 25_C) 511 Audio ICs FPin descriptions BA5210FS 512 Audio ICs BA5210FS 513 Audio ICs BA5210FS FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 3.3V RL = 8Ω, f= 1kHz and Rg = 600Ω) 514 Audio ICs FMeasurement circuit BA5210FS FApplication example 515 Audio ICs FOperation notes A characteristic of this IC is that if it is used with a supply voltage that is less than the recommended value (2.5V), the OUT-R offset increases.
