Description and Introduction

DIGITAL CONTROLLED STEREO AUDIO PROCESSOR The TDA7312 is a digital controlled stereo audio processor manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Type:** Digital controlled stereo audio processor  
- **Supply Voltage (VCC):** 8V to 10V (operating range)  
- **Total Harmonic Distortion (THD):** Typically 0.01% (at 1 kHz, 0 dB input level)  
- **Signal-to-Noise Ratio (SNR):** > 85 dB  
- **Channel Separation:** > 70 dB  
- **Control Interface:** I²C bus (serial control)  
- **Number of Inputs:** 4 stereo inputs  
- **Outputs:** Stereo line outputs  
- **Bass and Treble Control:** Adjustable via digital control  
- **Volume Control:** Digital control with mute function  
- **Package:** SO-20 (20-pin Small Outline package)  

### **Descriptions:**  
The TDA7312 is designed for high-quality audio processing in car radios and home audio systems. It allows digital control of volume, balance, bass, treble, and input selection through an I²C interface.  

### **Features:**  
- **4 stereo inputs** for flexible source selection  
- **Digital volume control** with mute function  
- **Bass and treble adjustment** with selectable frequency ranges  
- **Soft mute and zero-crossing detection** to minimize noise  
- **Low distortion and high signal-to-noise ratio** for high-fidelity audio  
- **I²C bus control** for easy integration with microcontrollers  

This device is commonly used in automotive infotainment systems and audio applications requiring digital control of audio processing.

Application Scenarios & Design Considerations

DIGITAL CONTROLLED STEREO AUDIO PROCESSOR

Alternative Part Number

  • PT2313L --: Audio tone/volume processor with I2C control and similar input/output channel count, commonly used as a direct substitute for TDA7312 in car and consumer audio designs.
  • TDA7439 --: Same ST audio processor family with I2C-controlled volume, tone and balance, offering comparable functionality and pin-compatible layout for many TDA7312 applications.
  • M62429P --: Serial-controlled audio volume/tone processor with similar analog signal path and supply range, usable as a functional replacement where exact pinout is adapted.
