Description and Introduction

Precision Voltage-to-Frequency Converter The LM331N is a precision voltage-to-frequency converter manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 4V to 40V  
- **Frequency Range:** 1Hz to 100kHz  
- **Linearity Error:** ±0.01% (typical)  
- **Temperature Stability:** ±50ppm/°C (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Output Drive Capability:** Open-collector output (sink up to 50mA)  
- **Power Consumption:** Low (typically 15mW at 5V)  

### **Descriptions:**
- The LM331N is a monolithic IC designed for accurate voltage-to-frequency conversion.  
- It is commonly used in analog-to-digital conversion, frequency-to-voltage conversion, and long-term integration applications.  
- The device provides high linearity and stability over a wide temperature range.  

### **Features:**
- **High Accuracy:** Excellent linearity (0.01%) and temperature stability.  
- **Wide Dynamic Range:** Operates from 1Hz to 100kHz.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Flexible Supply Voltage:** Works from 4V to 40V.  
- **Adjustable Scale Factor:** Allows customization via external resistors and capacitors.  
- **Open-Collector Output:** Compatible with TTL, CMOS, and other logic families.  

The LM331N is available in an 8-pin DIP package.
