Description and Introduction

Single-Chip Signal Processor for Color TV Use The LA7680 is an integrated circuit (IC) manufactured by SANYO. Below are the factual specifications, descriptions, and features based on available knowledge:

### **Specifications:**  
- **Manufacturer:** SANYO  
- **Function:** Video/Chrominance/Sync Signal Processor for TV Applications  
- **Package:** DIP (Dual In-line Package)  
- **Power Supply Voltage:** Typically **9V** (operating range may vary)  
- **Applications:** Used in color TV circuits for signal processing, including video, chroma, and sync functions.  

### **Descriptions:**  
- The LA7680 is a monolithic IC designed for TV signal processing, integrating multiple functions such as video amplification, chroma decoding, and sync separation.  
- It supports PAL and NTSC color systems.  
- Includes built-in circuits for automatic frequency and phase control (AFPC) for stable color processing.  

### **Features:**  
1. **Video Signal Processing:**  
   - Includes a video amplifier with contrast control.  
   - Features a built-in luminance (Y) signal processor.  

2. **Chroma (Color) Processing:**  
   - PAL/NTSC color demodulation.  
   - Automatic color killer (ACK) function.  
   - Integrated burst gate and color control circuits.  

3. **Sync Processing:**  
   - Horizontal and vertical sync separation.  
   - Noise immunity for stable synchronization.  

4. **Additional Functions:**  
   - AGC (Automatic Gain Control) for video signals.  
   - AFC (Automatic Frequency Control) for horizontal sync stability.  

This information is based on standard technical documentation for the LA7680 IC by SANYO. For precise electrical characteristics, refer to the official datasheet.
