Description and Introduction

PLL FM Multiplex Stereo Demodulator The LA3361 is an integrated circuit (IC) manufactured by Sanyo Semicon Device (now part of ON Semiconductor). It is primarily used in FM stereo demodulation applications.  

### **Specifications:**  
- **Function:** FM Stereo Demultiplexer (PLL Demodulator)  
- **Supply Voltage (Vcc):** 3.5V to 12V (typical operating range)  
- **Operating Current:** 10mA (typical at Vcc = 6V)  
- **Separation:** 45dB (typical)  
- **Total Harmonic Distortion (THD):** 0.3% (typical)  
- **Signal-to-Noise Ratio (S/N):** 70dB (typical)  
- **Package:** 16-pin DIP (Dual In-line Package)  

### **Descriptions and Features:**  
- Designed for FM stereo demodulation in radio receivers.  
- Uses a Phase-Locked Loop (PLL) for stable stereo decoding.  
- Includes a built-in stereo indicator (LED drive output).  
- Low distortion and high channel separation.  
- Compatible with direct connection to MPX (multiplex) signals from FM tuners.  
- Features a VCO (Voltage-Controlled Oscillator) for precise frequency control.  

This IC was commonly used in vintage stereo receivers and car audio systems.
