Application Scenarios & Design Considerations

FM IF AMPLIFIER WITH PILOT TONE DECODING FOR TV STEREO APPLICATIN

Alternative Part Number

  • SG3524N --: Classic PWM controller IC with the same regulating/modulating function as the TDA4940; widely available and well documented.
  • TL494CN --: Industry-standard PWM control circuit offering equivalent oscillator, error amplifier, and output stages for similar power-supply designs.
  • UC3842N --: Current-mode PWM controller commonly used as a functional substitute in switch-mode power supplies where the TDA4940 is applied.
  • TDA4940A --: Same TDA4940 series TV vertical deflection IC, pin-compatible and widely available from ST as a direct functional replacement.
  • TDA8172 --: Common vertical deflection output IC used in similar CRT TV chassis; check pinout and supply before substitution.
  • LA78040 --: Alternative vertical deflection IC from a different series, often used as a cross-reference for TDA4940-class circuits; verify pin compatibility.
