FOperation notes

(1) When the MUTE pin voltage reaches 1.5V or high-

er, the output voltage is muted and the bias level is out-

put.

(2) Frequency characteristics can be changed by ad-

justing the capacitor attached to pin 3 (pin18) or pin 5

(pin16).

(3) Gain can be changed by attaching a resistor to pin

4 (pin17).

(4) To prevent popping sounds due to sudden fluctua-

tion in the mute pin voltage, attach a capacitor (approxi-

mately 1µF) to pin 7.

(5) Be sure to connect the IC to a 0.1µF bypass capaci-

tor to the power supply, at the base of the IC.
