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.
