### **Specifications:**  
- **Supply Voltage (VCC):** 8V to 10V  
- **Operating Voltage Range:** 7V to 10.2V  
- **Total Harmonic Distortion (THD):** 0.01% (typical)  
- **Signal-to-Noise Ratio (SNR):** 95dB (typical)  
- **Number of Inputs:** 4 stereo inputs  
- **Number of Outputs:** 1 stereo output  
- **Control Interface:** I²C bus  
- **Package:** SO-20  

### **Descriptions:**  
The TDA7439D is a digital audio processor designed for high-quality audio applications. It provides functions such as input selection, volume control, bass/treble adjustment, balance, and loudness. It is controlled via an I²C interface, making it suitable for microprocessor-based systems.  

### **Features:**  
- **Input Selection:** 4 stereo inputs (switchable)  
- **Volume Control:** Adjustable in 1dB steps (0dB to -79dB)  
- **Bass & Treble Control:** Adjustable in 1dB steps (±14dB)  
- **Balance Control:** Adjustable in 1dB steps (L/R)  
- **Loudness Function:** Compensates for low-volume listening  
- **Mute Function:** Soft mute capability  
- **Low Distortion & High SNR:** Ensures high audio quality  
- **I²C Bus Control:** Allows easy integration with microcontrollers  

This information is based on the manufacturer's datasheet.
