FComplete application example circuit

FCircuit description

(1)

Power supply block

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

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

constant in this case.
