Description and Introduction

DIGITAL CONTROLLED STEREO AUDIO PROCESSOR The TDA7300D is an integrated circuit (IC) manufactured by STMicroelectronics. Below are the factual details about its specifications, descriptions, and features:  

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Type:** Digital Controlled Audio Processor  
- **Operating Voltage:** 8V to 18V (typical 12V)  
- **Current Consumption:** Typically 20mA (standby mode: 1µA)  
- **Signal-to-Noise Ratio (SNR):** Typically 90dB  
- **Total Harmonic Distortion (THD):** Typically 0.01%  
- **Number of Inputs:** 4 stereo inputs (or 8 mono)  
- **Number of Outputs:** 1 stereo output  
- **Control Interface:** I²C bus (for digital control)  
- **Package:** SO-20 (Small Outline 20-pin)  

### **Descriptions:**  
- The TDA7300D is designed for audio processing in car radio and multimedia systems.  
- It provides functions such as input selection, volume control, balance, fader, and tone control (bass/treble).  
- The IC supports digital control via the I²C interface, allowing microcontroller-based adjustments.  

### **Features:**  
- **Input Selector:** 4 stereo inputs (switchable)  
- **Volume Control:** Adjustable in 1dB steps (up to +15dB gain)  
- **Balance & Fader:** Adjustable left/right and front/rear balance  
- **Tone Control:** Adjustable bass and treble (±12dB)  
- **Standby Mode:** Low power consumption when inactive  
- **Soft Mute:** Smooth muting/unmuting  
- **Low Distortion:** High-quality audio processing  

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

Application Scenarios & Design Considerations

DIGITAL CONTROLLED STEREO AUDIO PROCESSOR

Alternative Part Number

  • LM1036N --: Audio tone/volume processor with similar tone and volume control functions, widely available and often used as a substitute in audio control circuits.
  • PT2313L --: Audio processor IC offering volume, tone, and balance control via I2C, functionally comparable to the TDA7300D in car and consumer audio systems.
  • TDA7439 --: Similar I2C-controlled audio processor with volume, tone, and balance features from the same family, suitable as a functional replacement with minor pin/register differences.
  • TDA7300 --: Same audio processor family in a different package (DIP vs SO), electrically compatible for most applications.
  • TDA7313D --: Similar ST audio processor with tone and volume control, often used as a drop-in substitute in audio systems.
