Description and Introduction

I2C-bus controlled economic BTSC stereo decoder and audio processor The TDA9853H is a digital controlled audio processor manufactured by PHILIPS (now NXP Semiconductors). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage (VCC):** 8V to 10V  
- **Operating Temperature Range:** -25°C to +85°C  
- **Package:** SDIP32 (Shrink Dual In-line Package, 32 pins)  
- **Control Interface:** I²C-bus (digital control)  
- **Signal-to-Noise Ratio (SNR):** Typically > 85 dB  
- **Total Harmonic Distortion (THD):** < 0.1%  

### **Descriptions:**  
- The TDA9853H is designed for high-quality audio processing in TV and multimedia applications.  
- It supports stereo sound processing with features like volume control, balance adjustment, and tone control (bass/treble).  
- The device includes an automatic volume leveler (AVL) and a loudness function for enhanced audio performance.  

### **Features:**  
- **Digital Control:** Adjustable via I²C-bus interface.  
- **Audio Processing Functions:**  
  - Volume, balance, bass, and treble control.  
  - Automatic Volume Leveler (AVL).  
  - Loudness compensation.  
  - Stereo/mono switching.  
- **Input/Output Flexibility:**  
  - Multiple audio inputs (SCART, AUX, etc.).  
  - Speaker and headphone outputs.  
- **Low Distortion:** Ensures high-fidelity sound output.  
- **Wide Supply Voltage Range:** Suitable for various applications.  

The TDA9853H is primarily used in television sets and audio systems requiring digital audio processing with minimal external components.

Application Scenarios & Design Considerations

I2C-bus controlled economic BTSC stereo decoder and audio processor

Alternative Part Number

  • TDA9853 --: Same TDA9853 audio processor family from the original Philips semiconductor business now branded NXP, with equivalent audio processing function and pin-compatible package options.
  • TDA9855 --: Closely related Philips/NXP TV audio processor in the same TDA98xx series, offering similar stereo audio decoding and I2C control for drop-in evaluation.
  • TDA8425 --: Philips/NXP I2C-controlled audio processor with comparable stereo sound processing features, usable as a functional substitute in TV audio designs.
  • TDA9853H/V1 --: NXP (formerly Philips) continued production of the TDA9853H audio processor; the /V1 variant is the same die with an updated revision and is a direct drop-in replacement.
  • MSP3410G --: Multistandard sound processor used in TV audio stages, providing comparable audio demodulation and processing as a cross-vendor alternative.
