TDA1593 - FM car radio receivers IF amplifier/demodulator

General Description

The TDA1593 provides IF amplification, symmetrical quadrature demodulation and level detection for quality FM car radio receivers and is suitable for mono and stereo reception.

It may also be applied to common front ends, stereo decoders and AM receivers circuits.

Key Features

  • Balanced limiting amplifier.
  • Balanced coincidence demodulator.
  • Two open-collector stop pulse outputs for microcomputer tuning control.
  • Simulated behaviour of ratio detector (internal field strength and detuning dependent voltage for dynamic AF signal muting).
  • Mono/stereo blend field strength indication control voltage.
  • AFC output.
  • Internal compensation of AF signal total harmonic distortion (THD).
  • Built-in hum and ripple re.
