Description and Introduction

3Digit A/D Converters with Bandgap Refrence and Charge-Pump Voltage Converter The MAX138CQH is a 12-bit, multichannel, successive approximation analog-to-digital converter (ADC) manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 12-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Conversion Time:** 3µs (max)  
- **Sampling Rate:** Up to 333ksps  
- **Input Voltage Range:** 0V to VREF (single-ended), ±VREF/2 (differential)  
- **Reference Voltage:** External (2.5V to VDD)  
- **Supply Voltage:** +5V ±10%  
- **Power Consumption:** 60mW (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 44-Pin PLCC  

### **Descriptions:**
- The MAX138CQH is a high-speed, low-power, 12-bit ADC with an internal track/hold circuit.  
- It supports both single-ended and differential input configurations.  
- The device features a parallel interface for easy integration with microprocessors.  
- It is designed for applications requiring high-speed, precision analog-to-digital conversion.  

### **Features:**
- **High-Speed Conversion:** 3µs conversion time.  
- **Flexible Input Configuration:** 8 single-ended or 4 differential channels.  
- **Internal Track/Hold:** Eliminates the need for an external sample-and-hold circuit.  
- **Low Power Consumption:** 60mW typical.  
- **Wide Reference Range:** Supports external references from 2.5V to VDD.  
- **Parallel Interface:** Easy interfacing with microcontrollers and DSPs.  
- **On-Chip Clock:** No external clock required.  

This information is based on the manufacturer's datasheet for the MAX138CQH.
