Description and Introduction

TONE CONTROL DIGITALLY CONTROLLED AUDIO PROCESSOR The TDA7449 is an audio processor manufactured by STMicroelectronics (ST). Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** STMicroelectronics (ST)  
- **Type:** Audio Processor (DSP-based)  
- **Supply Voltage (VCC):** 8V to 10V (operating range)  
- **Standby Current:** < 1 mA  
- **Signal-to-Noise Ratio (SNR):** > 85 dB  
- **Total Harmonic Distortion (THD):** < 0.01%  
- **Number of Inputs:** 4 stereo inputs (selectable)  
- **Number of Outputs:** 4-channel output (stereo + subwoofer)  
- **Control Interface:** I²C bus (for volume, balance, tone control, etc.)  
- **Package:** SO-28 (Surface Mount)  

### **Descriptions:**
- The TDA7449 is designed for high-quality audio processing in car audio systems and home entertainment applications.  
- It provides digital control over audio functions such as volume, balance, bass, treble, and fader.  
- The device supports multiple input selections and includes built-in soft mute functionality.  

### **Features:**
- **4 stereo inputs** with selection capability.  
- **4-channel output** (front L/R, rear L/R, or subwoofer configuration).  
- **I²C bus control** for adjusting audio parameters.  
- **Low standby current** for power efficiency.  
- **High SNR and low THD** for clear audio reproduction.  
- **Soft mute function** to eliminate switching noise.
