Description and Introduction

3 1/2 digit LCD/LED display A/D converter The ICL7107CM44 is a 3½ digit analog-to-digital converter (ADC) manufactured by Intersil (now Renesas Electronics). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Resolution:** 3½ digits (2000 counts)  
- **Input Type:** Differential  
- **Conversion Method:** Dual-slope integration  
- **Supply Voltage:** ±5V (dual supply)  
- **Reference Voltage:** Adjustable (typically 1V full scale)  
- **Display Output:** Directly drives 7-segment LED displays (common anode)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 44-pin PLCC (Plastic Leaded Chip Carrier)  

### **Descriptions:**  
- The ICL7107CM44 is a high-precision ADC designed for digital panel meters and measurement applications.  
- It includes an internal reference, clock, and display drivers, eliminating the need for external components in basic configurations.  
- The dual-slope conversion method ensures high noise rejection and accuracy.  

### **Features:**  
- **On-Chip Display Drivers:** Directly interfaces with 7-segment LED displays.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Auto-Zero Function:** Ensures accurate zero readings.  
- **High Input Impedance:** Reduces loading effects on the measured signal.  
- **Polarity Indication:** Displays positive or negative readings.  
- **Overrange Indication:** Shows "1" or "-1" when input exceeds full scale.  

This information is strictly based on the manufacturer's datasheet.
