Description and Introduction

Frequency to Voltage Converter The LM2907N is a frequency-to-voltage converter manufactured by National Semiconductor (NS). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage Range:** 12V to 28V (single supply)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Frequency Range:** 0Hz to 10kHz  
- **Output Voltage Swing:** Up to supply voltage minus 2V  
- **Quiescent Current:** 6mA (typical)  
- **Package:** 14-pin PDIP (Plastic Dual In-line Package)  

### **Descriptions:**  
- The LM2907N is a monolithic frequency-to-voltage converter with a high-gain 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.  
- The device includes a built-in zener regulator for stable operation.  

### **Features:**  
- **Frequency-to-Voltage Conversion:** Linear output proportional to input frequency.  
- **High Gain Op-Amp/Comparator:** Allows direct interfacing with digital or analog circuits.  
- **Built-in Zener Regulator:** Ensures stable operation without an external regulator.  
- **Wide Supply Voltage Range:** Operates from 12V to 28V.  
- **Robust Design:** Suitable for industrial and automotive applications.  

This information is based solely on the manufacturer's datasheet and technical documentation.
