Description and Introduction

V-F Converter The LM331 from STMicroelectronics is a precision voltage-to-frequency converter. Below are its key 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)  
- **Low Power Consumption:** 6mA (typical at 15V)  
- **Output Drive Capability:** Open-collector output (sink up to 50mA)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
- The LM331 is a highly stable monolithic voltage-to-frequency converter designed for precision applications.  
- It provides an accurate linear frequency output proportional to the input voltage.  
- Suitable for analog-to-digital conversion, frequency-to-voltage conversion, and long-term integration.  

### **Features:**  
- **High Linearity:** Excellent linearity over a wide frequency range.  
- **Wide Supply Range:** Operates from a single 5V supply up to 40V.  
- **Adjustable Scale Factor:** Frequency and full-scale range can be set with external resistors and capacitors.  
- **Low Temperature Drift:** Ensures stable performance across varying temperatures.  
- **Versatile Output:** Compatible with logic families (TTL, CMOS).  

This information is based on the manufacturer's datasheet for the LM331 by STMicroelectronics.
