Sound fader control circuit
Preliminary specification
TEA6323T
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 control with equalizer filters
• 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 TEA6323T is an I2C-bus
controlled stereo preamplifier for car radio hi-fi sound
applications.
