Description and Introduction

12 Bit A/D Converter With 3-State Binary Outputs The ICL7109CQH is a 12-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated (formerly Intersil). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Resolution:** 12-bit  
- **Conversion Method:** Dual-slope integrating ADC  
- **Supply Voltage:** Typically ±5V  
- **Reference Voltage:** Internal or external selectable  
- **Input Voltage Range:** ±4V (adjustable)  
- **Conversion Rate:** Up to 30 conversions per second  
- **Operating Temperature Range:** 0°C to +70°C (commercial grade)  
- **Package:** 40-pin CerDIP (Ceramic Dual In-line Package)  

### **Descriptions:**
- The ICL7109CQH is a high-precision, low-power, 12-bit ADC designed for applications requiring accurate analog-to-digital conversion.  
- It features auto-zero and polarity detection, making it suitable for instrumentation and measurement systems.  
- The dual-slope architecture ensures high noise immunity and low drift over temperature.  

### **Features:**
- **12-bit resolution** with no missing codes  
- **Low power consumption** (typically 10mW)  
- **Auto-zero and polarity detection**  
- **On-chip oscillator** for clock generation  
- **Serial and parallel output** options for interfacing with microcontrollers  
- **High noise rejection** due to dual-slope integration  
- **Internal or external reference voltage** selection  

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