Description and Introduction

Precision Voltage-to-Frequency Converter The LM131 is a precision voltage-to-frequency converter manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Supply Voltage Range:** ±15V (dual supply) or 4V to 40V (single supply)  
- **Frequency Linearity:** ±0.01% (typical)  
- **Temperature Drift:** ±50 ppm/°C (max)  
- **Output Frequency Range:** 1 Hz to 100 kHz  
- **Input Voltage Range:** 0V to VCC - 4V  
- **Power Consumption:** Low (typically 6 mA at 5V)  

### **Descriptions:**  
- The LM131 converts an analog input voltage into a corresponding frequency output.  
- It is designed for high accuracy and stability in applications like digital voltmeters, frequency-to-voltage conversion, and telemetry.  
- The device includes an internal precision reference and a temperature-compensated oscillator.  

### **Features:**  
- **High Linearity:** Ensures accurate frequency conversion over a wide range.  
- **Wide Supply Range:** Supports both single and dual power supplies.  
- **Low Power Consumption:** Suitable for battery-operated applications.  
- **Easy to Interface:** Compatible with TTL and CMOS logic.  
- **Stable Operation:** Minimizes drift due to temperature variations.  

The LM131 is commonly used in instrumentation, data acquisition, and signal processing systems.
