Preliminary specification
Sound fader control circuit
for car radios
TEA6330T
FEATURES
• Stereo/hi-fi processor for car radios performed with
volume, balance, bass and treble controls
• Sound fader control (front/rear) down to −30 dB in steps
of 2 dB
• Fast muting via bus or via setting the muting pin
GENERAL DESCRIPTION
• Suitable for external audio equalizers, can be looped-in
controlled by the I C-bus
2
2
This bipolar IC is an I C-bus controlled sound/volume
controller for car radios, in addition with fader function and
the possibility of an external equalizer.
• Power-on reset on chip sets the device into general
mute position
• AC and DC short-circuit protected concerning
neighbouring pins
2
• I C-bus control for all functions.
