TEA0679 - I2C-bus controlled dual Dolby* B-type noise reduction circuit for playback applications

Description

The TEA0679T is a bipolar integrated circuit that provides two channels of Dolby B noise reduction for playback applications in car radios.

It includes head and equalization amplifiers with electronically switchable time constants.

Features

  • Dual Noise Reduction (NR) channels.
  • Head preamplifiers.
  • Reverse head switching.
  • Automatic Music Search (AMS).
  • Blank skip.
  • Mute position.
  • Equalization with electronically switched time constants.
  • Switch functions and level adjustment controlled via I2C-bus.
  • Optional switch inputs TTL compatible.
  • Dolby reference level = 387.5 mV.
  • Contained in a 32-pin small outline package.
  • Improved EMC beh.
