Description and Introduction

THREE BANDS DIGITALLY CONTROLLED AUDIO PROCESSOR The TDA7438D is an integrated circuit (IC) manufactured by STMicroelectronics (ST). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** STMicroelectronics (ST)  
- **Type:** Digital Controlled Audio Processor  
- **Package:** SO-28 (Small Outline 28-pin)  
- **Operating Voltage:** 8V to 10V (typical)  
- **Supply Current:** 20mA (typical)  
- **Signal-to-Noise Ratio (SNR):** > 85dB  
- **Total Harmonic Distortion (THD):** < 0.01%  
- **Control Interface:** I²C Bus (Serial Control)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The TDA7438D is a digital audio processor designed for high-quality audio applications. It provides multiple audio processing functions, including volume control, tone adjustment (bass, treble, balance), and input selection. It is controlled via an I²C interface, making it suitable for microcontroller-based systems.

### **Features:**
- **4 Stereo Inputs:** Supports multiple audio sources.  
- **Programmable Gain:** Adjustable input and output levels.  
- **Tone Control:** Independent bass, treble, and balance adjustments.  
- **Volume Control:** Digital attenuation with mute function.  
- **Low Distortion:** High-fidelity audio processing.  
- **I²C Bus Control:** Allows easy integration with microcontrollers.  
- **Wide Supply Voltage Range:** Compatible with 8V–10V systems.  

This IC is commonly used in car audio systems, home theater setups, and other audio processing applications.
