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

• Suitable for external audio equalizers, can be looped-in

• Power-on reset on chip sets the device into general

mute position

• AC and DC short-circuit protected concerning

neighbouring pins
