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.
