Description and Introduction

LOW VOLTAGE TONE CONTROL DIGITALLY CONTROLLED AUDIO PROCESSOR The TDA7463A is a digital input audio processor manufactured by STMicroelectronics (STM).  

### **Specifications:**  
- **Type:** Digital Audio Processor  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SO-20 (Small Outline)  
- **Control Interface:** I²C Bus  
- **Signal-to-Noise Ratio (SNR):** > 90 dB  
- **Total Harmonic Distortion (THD):** < 0.01%  
- **Input Channels:** 4 stereo inputs (selectable)  
- **Output Channels:** 2 stereo outputs  
- **Digital Attenuation Range:** 0 dB to -79 dB (1 dB steps)  
- **Mute Function:** Software-controlled  

### **Descriptions:**  
The TDA7463A is designed for high-quality audio processing in applications such as car radios, home audio systems, and multimedia devices. It features digital volume control, input selection, and tone adjustments (bass/treble) via I²C interface.  

### **Features:**  
- **Input Selection:** 4 stereo inputs (configurable)  
- **Volume Control:** Digital attenuation with 1 dB steps  
- **Tone Control:** Adjustable bass and treble  
- **Mute Function:** Independent mute for each channel  
- **Low Distortion & Noise:** Ensures high-fidelity audio  
- **I²C Control Interface:** Allows easy integration with microcontrollers  
- **Wide Operating Voltage:** Compatible with 5V systems  

This device is ideal for applications requiring precise digital audio control with minimal external components.

Application Scenarios & Design Considerations

LOW VOLTAGE TONE CONTROL DIGITALLY CONTROLLED AUDIO PROCESSOR

Alternative Part Number

  • BD37534FV --: Audio sound processor with tone/volume control and 3-band equalizer, functionally similar to the TDA7463A audio processor and commonly used as a substitute in car audio designs.
  • PT2314 --: Four-channel audio processor with volume, tone, and input selection, offering comparable audio processing features for similar applications.
  • TDA7419 --: Higher-integration audio processor from the same vendor family with volume, tone, and loudness control, suitable when extra features are acceptable.
  • TDA7463D --: Same TDA7463 audio processor family in a different package variant, offering equivalent tone/volume control functionality with minimal redesign.
  • TDA7439 --: Similar ST audio processor with I2C-controlled tone and volume functions, suitable as a functional substitute in many audio applications.
