Preliminary specification
Sound fader control circuit
TEA6320
The power supply should include a VCC buffer capacitor,
which provides a discharging time constant. If the input
signal does not disappear after turn off the input will
become audible after certain time. A 4.7 kΩ resistor
discharges the VCC buffer capacitor, because the internal
current of the IC does not discharge it completely.
The hardware mute function is favourable for use in Radio
Data System (RDS) applications. The zero crossing mute
avoids modulation plops. This feature is an advantage for
mute during changing presets and/or sources (e.g. traffic
announcement during cassette playback).
