Sound fader control circuit

Preliminary specification

TEA6322T

FEATURES

• Source selector for three stereo and one differential

stereo input for remote sources

• The differential stereo input works optional as a fourth

stereo input and the common mode pin can be used as

well as an additional mono input

• Interface for noise reduction circuits

• Interface for external equalizer

• Volume, balance and fader control

• Output at volume I for external booster

• Special loudness characteristic automatically controlled

in combination with volume setting

• Bass and treble control

• Mute control at audio signal zero crossing

• Logic output to read mute status

• Fast mute control via I2C-bus

• Fast mute control via pin

• I2C-bus control for all functions

• Power supply with internal power-on reset

• Power-down indication.

GENERAL DESCRIPTION

The sound fader control circuit TEA6322T is an I2C-bus

controlled stereo preamplifier for car radio hi-fi sound

applications.
