Description and Introduction

Low-Cost, 2-Channel, ±14-Bit Serial ADCs The **MAX111BEWE+** 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  
- **Number of Channels:** 1 (single-ended)  
- **Interface Type:** Serial (SPI/QSPI/MICROWIRE compatible)  
- **Supply Voltage:** +5V  
- **Sampling Rate:** Up to **100 kSPS** (kilo-samples per second)  
- **Input Voltage Range:** 0V to VREF (programmable)  
- **Reference Voltage:** Internal (2.5V) or external (up to VDD)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** **SOIC-16** (Wide)  
- **Power Consumption:** 5mW (typical)  

### **Descriptions:**
- The MAX111BEWE+ is a low-power, high-performance 12-bit ADC with a serial interface.  
- It includes an internal track/hold, voltage reference, and clock, reducing external component requirements.  
- Suitable for battery-powered and portable applications due to its low power consumption.  

### **Features:**
- **Single-Supply Operation (+5V)**  
- **Internal 2.5V Reference** (or external reference support)  
- **SPI/QSPI/MICROWIRE-Compatible Serial Interface**  
- **Low Power:** 5mW (typical) at 100kSPS  
- **Small Footprint:** SOIC-16 package  
- **Software-Configurable Unipolar/Bipolar Input Range**  
- **Internal Track/Hold Function**  

This ADC is commonly used in data acquisition systems, industrial controls, and portable instrumentation.
