Sound fader control circuit

Preliminary specification

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).

LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134).
