BA3578FS / BA3579FS

FCircuit operation

(1) By operating the BA3578FS and BA3579FS according to the timing chart shown in Fig. 5, it is possible to suppress

generation of “pop” noise in the headphone output.

(2) The voltage of the BIAS pin (pin 11) for the BA3578FS and BA3579FS is the voltage divided from the AVDD pin

(pin 1). There is no current carrying capacity, so do not use it as an operating point for external circuits.
