FOperation notes

(1) By operating the BA3576FS according to the timing chart shown in Fig.3, it is possible to suppress generation of

“pop” noise in the headphone output.

(2) The BA3576FS ripple filter pins (1 and 2) and the bias amp pins (3 and 4) cannot be used as external power supplies

or reference voltages.

(3) The BEEP signal is only output when PWSTB (pin 7) and MUTE (pin 9) are high level. Also, input a rectangular

wave of between 500Hz and 5kHz and with an amplitude of VCC (with respect to ground) to BEEP IN (pin 11).
