TDA3866 - Quasi-split sound processor

General Description

Separate symmetrical IF inputs for FM or AM sound.

Gain controlled wideband IF amplifier, input select switch.

AGC generation due to peak sync for FM or mean signal level for AM.

Key Features

  • Quasi-split sound processor for all standards e. g. B/G (FM sound) and L (AM sound).
  • AF2 signal automatically muted (at B/G) by the input signal level.
  • AM signal processing for L standard and switching over the audio signal.
  • Stereo-matrix correction.
  • Layout-compatible with TDA3858 (32 pins) and TDA3857 (20 pins).
  • AM output level typically 500 mV at m = 0.54 (+2.5 dB in comparison to TDA3856).
