4 / 6 page 370 Audio ICs BA5152F FComplete application example circuit FCircuit description (1) Power supply block The BA5152F has an internal power switch, so the VCC terminal (pin 9) connects directly to the power source. Pin 13 is the power switch, and if it is left open, no bias current flows in the circuit and the IC will not operate. (2) Mute circuit block When pin 13 is connected to VCC, the IC starts up, but the mute circuit operates to suppress a “pop” sound from be- ing generated. The time constant of the power-on mute circuit is determined by the capacitor connected between pins 14 and 15. It is also possible to force the mute circuit to operate by connecting pin 16 to VCC. There is no time constant in this case. |
