Description and Introduction

Low Power, 3 Digit A/D Converter The ICL7137CQH is a 3½-digit analog-to-digital converter (ADC) manufactured by Maxim Integrated (formerly Intersil). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Resolution:** 3½ digits (2000 counts)  
- **Input Voltage Range:** ±200mV or ±2V (selectable)  
- **Conversion Rate:** ~3 readings per second  
- **Supply Voltage:** Typically ±5V (dual supply)  
- **Reference Voltage:** Internal or external (adjustable)  
- **Display Drive:** Directly drives 7-segment LCD displays  
- **Low Power Consumption:** ~1mW  
- **Operating Temperature Range:** 0°C to +70°C (commercial grade)  
- **Package:** 40-pin CerDIP (ICL7137CQH)  

### **Descriptions:**  
- The ICL7137CQH is a precision ADC designed for low-power, high-accuracy digital panel meter applications.  
- It includes auto-zeroing, polarity detection, and overrange/underrange indication.  
- The device integrates all necessary functions for driving an LCD display, eliminating the need for external decoding logic.  

### **Features:**  
- **Auto-Zero:** Ensures zero reading for zero input.  
- **True Differential Input:** Rejects common-mode noise.  
- **High Input Impedance:** >10¹²Ω (minimizes loading effects).  
- **Low Noise:** Typically <15µV peak-to-peak.  
- **On-Chip Reference:** Requires minimal external components.  
- **Overrange/Underrange Output:** Indicates readings beyond full scale.  
- **Single-Polarity Power Supply Option:** Can operate with a single +5V supply (with external reference).
