TDA7040T is a monolithic integrated FM stereo demodulator manufactured by PHILIPS (now NXP Semiconductors).

The TDA7040T is a monolithic integrated FM stereo demodulator manufactured by PHILIPS (now NXP Semiconductors). Below are its key specifications, descriptions, and features based on factual data:

Specifications:

  • Supply Voltage (VCC): 3–8.5V
  • Operating Current: 6 mA (typical)
  • Input Frequency Range: Up to 1 MHz
  • Signal-to-Noise Ratio (SNR): 60 dB (typical)
  • Channel Separation: 35 dB (typical)
  • Total Harmonic Distortion (THD): 0.3% (typical)
  • Operating Temperature Range: -25°C to +85°C
  • Package: SO16 (Small Outline 16-pin)

Descriptions:

  • The TDA7040T is designed for FM stereo demodulation in portable radios and audio systems.
  • It includes a phase-locked loop (PLL) for stereo decoding with low distortion.
  • No external coils are required for stereo decoding, simplifying circuit design.
  • Suitable for battery-operated devices due to low power consumption.

Features:

  • Integrated PLL Demodulator: Ensures stable stereo decoding.
  • Low Power Consumption: Ideal for portable applications.
  • Mono/Stereo Switching: Automatic or manual control.
  • Soft Mute Function: Reduces noise during weak signal conditions.
  • Few External Components Required: Simplifies PCB design.
  • High Ripple Rejection: Reduces interference from power supply.

This information is based solely on the manufacturer’s datasheet and technical documentation.
