Description and Introduction

Frequency to Voltage Converter The LM2917N-14 is a frequency-to-voltage converter manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Supply Voltage Range:** 3V to 28V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Frequency Range:** 0Hz to 10kHz (typical)  
- **Output Voltage Range:** Proportional to input frequency  
- **Package:** 14-Pin PDIP (Plastic Dual In-Line Package)  
- **Internal Zener Diode:** Provides regulated supply (7.56V typical)  
- **Low Standby Current:** 1.5mA (typical)  
- **High Output Drive:** Up to 50mA  

### **Descriptions:**  
The LM2917N-14 is a monolithic frequency-to-voltage converter with a built-in op-amp/comparator. It is designed to generate an output voltage proportional to the input frequency, making it useful in tachometer, speedometer, and other frequency-sensing applications.  

### **Features:**  
- **Frequency-to-Voltage Conversion:** Linear output proportional to input frequency  
- **Built-in Op-Amp/Comparator:** Allows flexible signal conditioning  
- **On-Chip Zener Regulator:** Ensures stable operation  
- **Wide Supply Voltage Range:** Suitable for automotive and industrial applications  
- **High Output Current Capability:** Can drive relays, meters, or other loads directly  

This device is commonly used in automotive, industrial, and instrumentation applications where frequency measurement is required.
