Description and Introduction

TONE CONTROL DIGITALLY CONTROLLED AUDIO PROCESSOR The TDA7440D is an integrated circuit (IC) manufactured by STMicroelectronics (STM). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** STMicroelectronics (STM)  
- **Type:** Audio Processor IC  
- **Package:** SO-20 (Small Outline, 20 pins)  
- **Operating Voltage:** 8V to 10V (typical)  
- **Supply Current:** 10mA (typical)  
- **Signal-to-Noise Ratio (SNR):** 90dB (typical)  
- **Total Harmonic Distortion (THD):** 0.01% (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The TDA7440D is a high-performance audio processor designed for car radio and audio applications. It provides multiple audio processing functions, including volume control, tone adjustment (bass/treble), balance, and fader control. The IC is controlled via an I²C serial bus interface, allowing for easy integration into digital audio systems.  

### **Features:**  
- **Volume Control:** Adjustable in 1dB steps (up to 79dB range)  
- **Bass & Treble Control:** Adjustable in 2dB steps (±14dB range)  
- **Balance & Fader Control:** Adjustable in 1dB steps (up to 15dB range)  
- **I²C Bus Interface:** Allows digital control of all functions  
- **Low Distortion & High SNR:** Ensures high-quality audio output  
- **Mute Function:** Soft mute capability for noise-free operation  
- **Standby Mode:** Low power consumption when inactive  

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