Description and Introduction

Multi-Range (【10V, 【5V, +10V, +5V), Single +5V, 12-Bit DAS with 8+4 Bus Interface The MAX197AEWI is a 12-bit, multirange, data-acquisition system (DAS) manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Resolution:** 12-bit  
- **Input Channels:** 8 single-ended or 4 differential  
- **Conversion Time:** 6µs (max)  
- **Throughput Rate:** 100ksps  
- **Input Voltage Ranges:**  
  - ±10V, ±5V (bipolar)  
  - 0V to +10V, 0V to +5V (unipolar)  
- **Supply Voltage:** ±5V  
- **Power Consumption:** 100mW (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin Wide SOIC  

### **Descriptions:**  
The MAX197AEWI integrates an 8-channel multiplexer, a high-bandwidth track/hold, and a 12-bit successive-approximation ADC. It supports both unipolar and bipolar input ranges, making it suitable for industrial and instrumentation applications.  

### **Features:**  
- **Multirange Inputs:** Software-selectable unipolar/bipolar ranges.  
- **Internal/External Clock:** Configurable for flexibility.  
- **Internal 4.096V Reference:** Eliminates the need for an external reference.  
- **Parallel Interface:** Easy interfacing with microprocessors.  
- **Low Power:** 100mW typical power consumption.  
- **Track/Hold Function:** 1.5MHz full-power bandwidth.  

This device is commonly used in data acquisition, industrial control, and test equipment applications.
