Description and Introduction

DIGITALLY CONTROLLED AUDIO PROCESSOR WITH SURROUND SOUND MATRIX AND VOICE CANCELLER The TDA7431 is a digital-controlled audio processor manufactured by STMicroelectronics. Here are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

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

### **Descriptions:**  
The TDA7431 is a digital audio processor designed for high-quality audio applications. It provides functions such as input selection, volume control, bass/treble adjustment, and loudness compensation. It is controlled via an I²C interface, making it suitable for microcontroller-based systems.  

### **Features:**  
- **Input Selection:** 4 stereo inputs (switchable)  
- **Volume Control:** Adjustable in 1 dB steps (0 dB to -79 dB)  
- **Bass & Treble Control:** Adjustable in 1 dB steps (±14 dB)  
- **Loudness Compensation:** Adjustable for low-volume listening  
- **Mute Function:** Software-controllable mute for each channel  
- **Low Distortion & Noise:** Ensures high-fidelity audio processing  
- **I²C Bus Control:** Allows easy integration with microcontrollers  

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