Description and Introduction

Multirange, +5V, 12-Bit DAS with 2-Wire Serial Interface The MAX127BENG is a 12-bit, 8-channel, serial 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)  
- **Input Voltage Range:**  
  - ±10V (bipolar mode)  
  - 0V to +10V (unipolar mode)  
- **Interface:** Serial (SPI/QSPI/MICROWIRE compatible)  
- **Supply Voltage:**  
  - **Analog Supply (VDD):** +5V ±5%  
  - **Digital Supply (VCC):** +2.7V to +5.25V  
- **Power Consumption:**  
  - **Operating Mode:** 3.5mA (typical)  
  - **Shutdown Mode:** 2µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin DIP (Dual In-line Package)  

### **Descriptions:**  
The MAX127BENG is a high-performance, low-power, multichannel ADC designed for precision data acquisition applications. It supports both unipolar and bipolar input ranges, making it versatile for industrial and instrumentation use. Its serial interface allows easy integration with microcontrollers and DSPs.

### **Features:**  
- **Flexible Input Configuration:**  
  - 8 single-ended or 4 differential inputs  
  - Software-selectable unipolar/bipolar ranges  
- **Low Power Consumption:**  
  - 3.5mA operating current  
  - 2µA shutdown mode  
- **Internal 4.096V Reference:**  
  - Eliminates the need for an external reference  
- **Built-in Track/Hold:**  
  - No external sample-and-hold required  
- **SPI-Compatible Serial Interface:**  
  - 3-wire communication (CS, SCLK, DIN/DOUT)  
- **Hardware Shutdown Mode:**  
  - Reduces power consumption when inactive  
- **Robust Packaging:**  
  - 24-pin DIP for easy prototyping and industrial use  

This ADC is suitable for applications such as industrial process control, data logging, and medical instrumentation.
