Description and Introduction

31/2 Digit/ LCD/LED Display/ A/D Converter with Display Hold The ICL7116CM44 is a 3½ digit analog-to-digital converter (ADC) manufactured by Harris Semiconductor (now part of Intersil/Renesas). Below are the key specifications, descriptions, and features based on the available knowledge base:

### **Manufacturer:**  
- **Harris Semiconductor** (now part of Intersil/Renesas)  

### **Key Specifications:**  
- **Resolution:** 3½ digits (2000 counts)  
- **Input Type:** Differential  
- **Supply Voltage:** Typically ±5V (dual supply)  
- **Reference Voltage:** Adjustable (typically 100mV or 1V)  
- **Conversion Rate:** ~3 readings per second  
- **Display Driver:** Directly drives LCD displays  
- **Input Impedance:** >1GΩ  
- **Operating Temperature Range:** 0°C to +70°C (commercial grade)  
- **Package:** 44-pin PLCC (Plastic Leaded Chip Carrier)  

### **Descriptions:**  
- The ICL7116CM44 is a precision ADC designed for low-power digital panel meter applications.  
- It includes an internal voltage reference, clock oscillator, and LCD driver circuitry.  
- It is commonly used in digital multimeters, process control systems, and instrumentation.  
- The device provides auto-zeroing and true differential input for accurate measurements.  

### **Features:**  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **Auto-Polarity:** Automatically detects and displays positive or negative input voltages.  
- **Auto-Zeroing:** Eliminates offset errors for improved accuracy.  
- **On-Chip Reference:** Reduces external component count.  
- **Direct LCD Drive:** Simplifies display interfacing.  
- **High Input Impedance:** Minimizes loading effects on measured signals.  

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

Application Scenarios & Design Considerations

31/2 Digit/ LCD/LED Display/ A/D Converter with Display Hold

Alternative Part Number

  • TC7106CPL --: Pin-compatible 3.5-digit ADC with similar functionality and widely available; different series naming makes it easy to distinguish.
  • ICL7106CPL --: Same ICL7106 family function as the ICL7116, direct functional equivalent from the original Intersil line now under Renesas.
  • MAX130CPL --: 3.5-digit A/D converter with comparable display-driver function, offered as an alternative from a different series.
  • MC14433P --: Alternative 3.5-digit A/D converter with multiplexed BCD output; suitable when the design can adapt to its output format and supply requirements.
