TEA6330T - Sound fader control circuit for car radios

Description

This bipolar IC is an I2C-bus controlled sound/volume controller for car radios, in addition with fader function and the possibility of an external equalizer.

1.

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 controlled by the I2C-bus.
  • Power-on reset on chip sets the device into general mute position.
  • AC and DC short-circuit protected concerning neighbouring pins.
