Description and Introduction

DIGITAL CONTROLLED AUDIO PROCESSOR WITH SURROUND SOUND MATRIX The TDA7344P is an integrated circuit (IC) manufactured by STMicroelectronics (STM). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
STMicroelectronics (STM)  

### **Specifications:**  
- **Type:** Audio Processor IC  
- **Package:** DIP-28 (Dual In-line Package, 28 pins)  
- **Operating Voltage:** 8V to 18V (typical 12V)  
- **Current Consumption:** ~30mA (typical)  
- **Signal-to-Noise Ratio (SNR):** >80dB  
- **Total Harmonic Distortion (THD):** <0.1%  
- **Input Channels:** 4 (stereo inputs)  
- **Output Channels:** 4 (stereo outputs)  
- **Control Interface:** I²C (serial bus control)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The TDA7344P is a high-performance audio processor designed for car radio and audio system applications. It provides features such as volume control, balance, fader, tone control (bass/treble), and loudness compensation. The IC is controlled via an I²C interface, allowing for digital adjustment of audio parameters.  

### **Features:**  
- **Volume Control:** Digital adjustment with soft mute  
- **Balance & Fader:** Independent control for front/rear and left/right channels  
- **Tone Control:** Adjustable bass and treble levels  
- **Loudness Function:** Enhances low and high frequencies at low volume  
- **Input Selector:** Supports up to 4 stereo inputs  
- **Low Distortion & High SNR:** Ensures high-quality audio output  
- **Protection Circuits:** Includes short-circuit and thermal protection  

This information is based on the official STMicroelectronics datasheet for the TDA7344P.

Application Scenarios & Design Considerations

DIGITAL CONTROLLED AUDIO PROCESSOR WITH SURROUND SOUND MATRIX

Alternative Part Number

  • TDA7342 --: Same TDA73xx audio processor family with similar pinout and function, often used as a direct substitute in audio switching applications.
  • TDA7439 --: Comparable ST audio processor with I2C control and similar tone/volume features, suitable for many TDA7344P designs with minor circuit checks.
  • PT2313L --: Widely used audio processor IC with similar volume, tone and input selection functions, commonly cross-referenced for TDA7344P replacements.
