Description and Introduction

Quasi Parallel Sound Processing with Quadrature Intercarrier Demodulator The TDA4445B is a monolithic integrated circuit manufactured by STMicroelectronics (ST). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** STMicroelectronics (ST)  
- **Package:** DIP-16 (Dual In-line Package with 16 pins)  
- **Technology:** Bipolar  
- **Supply Voltage (VCC):** 5V (typical)  
- **Operating Temperature Range:** -20°C to +70°C  

### **Descriptions:**  
The TDA4445B is a video intermediate frequency (VIF) amplifier and demodulator IC designed for TV applications. It includes functions such as amplification, synchronous demodulation, and automatic gain control (AGC) for processing the IF signal in television receivers.  

### **Features:**  
- **VIF Amplifier:** High-gain amplifier for intermediate frequency signals.  
- **Synchronous Demodulator:** Ensures accurate demodulation of the video signal.  
- **AGC (Automatic Gain Control):** Provides stable output under varying input signal levels.  
- **Sound IF Output:** Includes a separate output for sound IF signals.  
- **Low Power Consumption:** Optimized for efficient operation in TV circuits.  

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

- **Frequency Range:** Designed for Intermediate Frequency (IF) processing, commonly used in TV and video applications.  
- **Demodulation:** Includes FM demodulation for sound and video signal processing.  

### **Descriptions:**  
The TDA4445B is a monolithic integrated circuit designed for use in television and video applications. It functions as a video IF amplifier and demodulator, processing intermediate frequency signals to extract video and sound components.  

### **Features:**  
- **Video IF Amplification:** Provides high gain for weak IF signals.  
- **Synchronous Demodulation:** Ensures accurate video signal recovery.  
- **FM Sound Demodulation:** Includes circuitry for sound IF processing.  
- **AGC (Automatic Gain Control):** Maintains stable signal levels.  
- **Low Noise:** Designed for minimal signal distortion.  

For exact electrical characteristics, pin configurations, or application circuits, refer to the official TFK datasheet (if available).
