Description and Introduction

DIGITAL CONTROLLED STEREO AUDIO PROCESSOR WITH LOUDNESS The TDA7313 is an integrated circuit (IC) manufactured by SGS-THOMSON (now STMicroelectronics).  

### **Specifications:**  
- **Function:** Digital Controlled Audio Processor  
- **Channels:** 4-channel input selector with volume, balance, bass, treble, and loudness control  
- **Supply Voltage:** 8V to 10V (typical)  
- **Operating Voltage Range:** 6V to 12V  
- **Total Harmonic Distortion (THD):** Low distortion levels (exact value depends on application conditions)  
- **Signal-to-Noise Ratio (SNR):** High SNR for clear audio processing  
- **Control Interface:** I²C bus for digital control  
- **Package:** Typically available in DIP (Dual In-line Package) or SO (Small Outline)  

### **Descriptions and Features:**  
- **Input Selection:** Allows switching between four stereo input channels.  
- **Volume Control:** Digitally controlled with adjustable range.  
- **Tone Control:** Independent bass and treble adjustment.  
- **Balance Control:** Adjusts left/right channel balance.  
- **Loudness Function:** Enhances bass at low volume levels.  
- **Mute Function:** Soft mute capability for noise-free operation.  
- **Low Standby Current:** Suitable for power-efficient applications.  

The TDA7313 is commonly used in car audio systems and home stereo equipment for digital audio processing.  

(Note: For exact electrical characteristics, refer to the official datasheet from STMicroelectronics.)

Application Scenarios & Design Considerations

DIGITAL CONTROLLED STEREO AUDIO PROCESSOR WITH LOUDNESS

Alternative Part Number

  • PT2313L --: Pin-compatible audio processor with similar tone/volume/balance control functions, widely used as a direct substitute for TDA7313 in car and consumer audio designs.
  • TDA7439 --: Same manufacturer family audio processor with I2C control and comparable input/output switching and tone control, suitable when minor pin/register differences can be accommodated.
  • PT2314 --: Similar multi-input audio processor with volume, tone and balance control, often used as an alternative in designs originally based on the TDA7313.
  • TDA7313D --: Same audio processor family from the successor of SGS-Thomson, in SO package; functionally equivalent with identical tone/volume control features.
  • TDA7318 --: Pin-compatible audio processor with similar I2C control and tone/volume functions, often used as a drop-in substitute in car radio designs.
  • TDA7419 --: Same manufacturer family audio processor offering comparable multi-channel tone and volume control with I2C interface, suitable upgrade with minor circuit adaptation.
  • LV1116 --: Similar audio signal processor for volume, balance, and tone control in audio systems, usable as a functional alternative with pinout verification.
