Description and Introduction

LM566C Voltage Controlled Oscillator The LM566 is a voltage-controlled oscillator (VCO) manufactured by National Semiconductor (NSC). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Supply Voltage Range:** 10V to 24V  
- **Frequency Range:** Up to 1 MHz  
- **Temperature Range:** 0°C to +70°C  
- **Frequency Linearity:** ±0.2% typical  
- **Frequency Drift with Temperature:** 300 ppm/°C typical  
- **Output Voltage Swing:** Adjustable, typically rail-to-rail  
- **Modulation Sensitivity:** Adjustable via external resistor/capacitor  

### **Descriptions:**  
- The LM566 is a monolithic VCO designed for precision frequency generation.  
- It can be used in FM modulation, tone generation, and frequency-shift keying (FSK) applications.  
- The frequency is controlled by an external resistor, capacitor, and modulating input voltage.  

### **Features:**  
- **Voltage-Controlled Oscillator (VCO):** Frequency is linearly adjustable via control voltage.  
- **Square and Triangle Wave Outputs:** Provides both waveforms simultaneously.  
- **High Temperature Stability:** Low frequency drift over temperature.  
- **Wide Supply Voltage Range:** Operates from 10V to 24V.  
- **Easy Frequency Adjustment:** External resistor and capacitor allow tuning.

Description and Introduction

LM566C Voltage Controlled Oscillator The LM566 is a voltage-controlled oscillator (VCO) IC manufactured by **Texas Instruments** (formerly National Semiconductor). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** 10V to 24V (single supply)  
- **Operating Frequency Range:** Up to **1 MHz**  
- **Frequency Linearity:** Typically **±0.2%**  
- **Temperature Stability:** **150 ppm/°C**  
- **Output Waveforms:** **Square wave** and **triangle wave**  
- **Modulation Input:** Voltage-controlled frequency adjustment  
- **Power Consumption:** Typically **4.5 mA** at 12V  

### **Description:**  
The LM566 is a monolithic VCO designed for precision frequency generation. It operates by converting an input control voltage into a proportional output frequency. The IC is commonly used in applications like tone generation, FM modulation, and phase-locked loops (PLLs).

### **Features:**  
- **Wide Supply Voltage Range** (10V–24V)  
- **High Frequency Stability**  
- **Simultaneous Square and Triangle Wave Outputs**  
- **Linear Frequency Modulation**  
- **Low Power Consumption**  
- **Easy to Use with Minimal External Components**  

For exact performance details, refer to the official **LM566 datasheet** from Texas Instruments.
