Description and Introduction

3 1/2 Digit LCD/LED, Low Power Display, A/D Converters with Overrange Recovery The **ICL7136** is a low-power, 3½-digit analog-to-digital converter (ADC) designed for precision measurement applications. Below are its key specifications, descriptions, and features:

### **Manufacturer**  
- **Intersil** (now part of Renesas Electronics)  

### **Key Features**  
1. **Low Power Consumption**  
   - Typically draws **100 µA** (ideal for battery-operated devices).  

2. **3½-Digit Resolution**  
   - Provides **±1999 counts** display range.  

3. **Auto-Zero and Auto-Polarity**  
   - Automatically corrects for zero offsets and detects input polarity.  

4. **High Input Impedance**  
   - Input leakage current of **1 pA** (minimizes loading effects).  

5. **On-Chip Reference**  
   - Includes an internal **2.8V bandgap reference** (adjustable).  

6. **Single-Power Supply Operation**  
   - Operates from a **single 9V battery** (typically **±5V** supply range).  

7. **Seven-Segment Decoder and Display Drivers**  
   - Directly drives **LCD displays** (no external decoder needed).  

8. **Low Noise**  
   - **15 µV peak-to-peak noise** for stable readings.  

9. **True Differential Input**  
   - Supports **differential voltage measurements**.  

10. **Overrange and Underrange Indication**  
    - Flags readings beyond **±1999 counts**.  

### **Applications**  
- Digital multimeters (DMMs)  
- Portable instrumentation  
- Battery-powered measurement devices  
- Process control systems  

### **Package Options**  
- **40-pin DIP (Dual Inline Package)**  
- **44-pin PLCC (Plastic Leaded Chip Carrier)**  

This information is based strictly on the datasheet and manufacturer specifications. Let me know if you need further details.
