Description and Introduction

Multirange / +5V / 8-Channel / Serial 12-Bit ADCs The MAX1271AENG is a 12-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 12-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Sampling Rate:** Up to 110ksps (kilo samples per second)  
- **Supply Voltage:** +5V  
- **Input Voltage Range:**  
  - **Single-Ended:** 0V to +5V  
  - **Differential:** ±VREF (programmable)  
- **Reference Voltage:** Internal (4.096V) or external (1V to VDD)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin DIP  

### **Descriptions:**
The MAX1271AENG is a high-performance, low-power, 12-bit ADC with a successive-approximation register (SAR) architecture. It features a flexible input configuration (single-ended or differential) and includes an internal reference. The device is designed for applications requiring high accuracy and moderate speed, such as industrial control, data acquisition, and instrumentation.

### **Features:**
- **Low Power Consumption:** 2.5mA (operating), 2µA (shutdown)  
- **Internal 4.096V Reference** (with ±1% accuracy)  
- **Software-Configurable Inputs:** Single-ended or differential  
- **No External Components Required** for basic operation  
- **SPI-Compatible Serial Interface** (3-wire mode)  
- **Built-In Track/Hold Function**  
- **Small Footprint:** Available in 24-pin DIP and SO packages  

This ADC is suitable for precision measurement applications where low power and ease of integration are critical.
