Description and Introduction

RDS FILTER The TDA7332D is a digital controlled stereo audio processor manufactured by SGS-THOMSON (now STMicroelectronics). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** SGS-THOMSON (STMicroelectronics)  
- **Type:** Digital Controlled Stereo Audio Processor  
- **Package:** SO-20 (Small Outline 20-pin)  
- **Supply Voltage (VCC):** 8V to 10.8V (typical 9V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Total Harmonic Distortion (THD):** < 0.5% (typical)  
- **Signal-to-Noise Ratio (SNR):** > 70dB  

### **Descriptions:**  
- The TDA7332D is designed for high-quality stereo audio processing in car radio and audio systems.  
- It includes digital control for functions like volume, balance, fader, and tone adjustments (bass/treble).  
- The IC integrates input selectors, preamplifiers, and tone control circuits.  

### **Features:**  
- **Digital Control Interface:** I²C bus for volume, balance, fader, and tone adjustments.  
- **Input Selector:** Multiple stereo inputs (typically 3 or 4).  
- **Tone Control:** Adjustable bass and treble settings.  
- **Volume Control:** Wide attenuation range (up to -80dB).  
- **Low Standby Current:** Suitable for battery-powered applications.  
- **Built-in Preamplifiers:** For direct connection to external sources.  

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

Application Scenarios & Design Considerations

RDS FILTER

Alternative Part Number

  • TDA7333D --: Same TDA733x family stereo decoder with similar function and pinout, often used as a direct upgrade in audio decoder applications.
  • TDA7342D --: Related ST audio processor in the same TDA73xx series with comparable supply voltage and signal processing features.
  • TDA7439 --: Similar ST audio control/decoder IC with compatible audio processing role, usable as a functional substitute in many designs.
  • TDA7330B --: Related ST stereo decoder IC in the TDA733x series with comparable audio decoding functionality and supply requirements.
  • TDA7342 --: ST audio processor with similar decoder/processing role, suitable as a functional substitute where minor pin differences can be accommodated.
  • TDA7332 --: Same TDA7332 function from the successor company STMicroelectronics; the D suffix only denotes the package, so the base device is a direct functional match.
  • TDA7330 --: Closely related TDA733x family device with similar audio processing function; check pinout and package before substitution.
  • TDA7333 --: Another member of the same TDA733x series with comparable functionality; verify electrical specifications and package compatibility.
  • SAA6579 --: RDS demodulator IC from the same original vendor lineage, suitable as a fallback alternative after checking pinout and supply voltage.
