Description and Introduction

DIGITALLY CONTROLLED AUDIO PROCESSOR WITH SURROUND SOUND MATRIX AND VOICE CANCELLER The TDA7430 is a digital controlled audio processor manufactured by STMicroelectronics (STM).  

### **Specifications:**  
- **Supply Voltage (VCC):** 8V to 10V  
- **Operating Voltage Range:** 7V to 10.2V  
- **Standby Current:** < 1mA  
- **Total Harmonic Distortion (THD):** < 0.01%  
- **Signal-to-Noise Ratio (SNR):** > 90dB  
- **Number of Inputs:** 4 stereo inputs  
- **Number of Outputs:** 1 stereo output  
- **Control Interface:** I²C bus  
- **Package:** SO-20  

### **Descriptions:**  
The TDA7430 is a digital audio processor designed for high-quality audio applications. It features four stereo inputs, tone control (bass, treble), volume control, balance, and loudness functions. The device is controlled via an I²C bus, allowing for easy integration into digital audio systems.  

### **Features:**  
- **4 stereo inputs** (selectable via I²C)  
- **Bass and treble control** (adjustable in steps)  
- **Volume control** (with mute function)  
- **Balance adjustment** (left/right)  
- **Loudness function** (compensates for low-volume listening)  
- **Low distortion and high SNR** for high-fidelity audio  
- **I²C bus control** for digital interfacing  
- **Wide supply voltage range** (7V to 10.2V)  

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

Application Scenarios & Design Considerations

DIGITALLY CONTROLLED AUDIO PROCESSOR WITH SURROUND SOUND MATRIX AND VOICE CANCELLER

Alternative Part Number

  • PT2313L --: Audio processor with tone and volume control functions similar to the TDA7430, commonly used as a direct functional substitute in audio systems.
  • TDA7440 --: Same ST audio processor family with comparable I2C-controlled tone and volume features, offering close pin and function compatibility.
  • LM1036N --: Analog tone and volume control IC providing similar audio processing capability, suitable for designs needing a simpler non-I2C alternative.
