Description and Introduction

Frequency to Voltage Converter 14-PDIP -40 to 85 The LM2907N/NOPB is a frequency-to-voltage converter manufactured by National Semiconductor (NSC). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Supply Voltage Range:** 12V to 28V (single supply)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Frequency Input Range:** Up to 10kHz  
- **Output Voltage Swing:** Near ground to VCC - 2V  
- **Quiescent Current:** 6mA (typical)  
- **Package Type:** PDIP-14 (Plastic Dual In-Line Package)  

### **Descriptions:**  
- The LM2907N/NOPB converts an input frequency signal into a proportional DC output voltage.  
- It includes an op-amp/comparator, a charge pump, and a high-gain output amplifier.  
- Designed for automotive and industrial applications, including speed sensing, RPM measurement, and frequency-based control systems.  

### **Features:**  
- **Frequency-to-Voltage Conversion:** Linear output proportional to input frequency.  
- **Built-in Op-Amp/Comparator:** Allows flexible signal conditioning.  
- **High Output Drive:** Capable of sourcing up to 50mA.  
- **Wide Supply Voltage Range:** Suitable for 12V and 24V systems.  
- **Ground-Referenced Input:** Compatible with various signal sources.  
- **Internal Zener Regulator:** Provides stable operation under varying supply conditions.  

This device is RoHS-compliant and is commonly used in tachometers, speedometers, and other frequency-based measurement systems.
