Fig.1 Block diagram and application circuit.
(1) Connecting pin 13 to ground is only allowed for measuring the current at pin 16. It is not for use in application.
(2) In the FM, mute-on condition the unweighted level detector output is available from pin 3. In the FM, mute-off condition the variable resistor at pin 3 can be adjusted for
minimum 2nd harmonic distortion at pin 4.
