Description and Introduction

Multi-Range (【10V, 【5V, +10V, +5V), Single +5V, 12-Bit DAS with 8+4 Bus Interface The MAX197BEWI is a 12-bit, multirange, data acquisition system (DAS) manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 12-bit  
- **Input Channels:** 8 single-ended or 4 differential  
- **Conversion Time:** 6µs (max)  
- **Sampling Rate:** Up to 100ksps  
- **Input Voltage Ranges:**  
  - ±10V, ±5V, 0 to +10V, 0 to +5V (software-selectable)  
- **Power Supply:** +5V (analog), +5V (digital)  
- **Power Consumption:** 100mW (typical)  
- **Interface:** Parallel (8-bit µP-compatible)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin wide SOIC  

### **Descriptions:**
The MAX197BEWI integrates a 12-bit successive-approximation ADC, a track/hold amplifier, and a versatile input multiplexer. It supports multiple input ranges, making it suitable for industrial and instrumentation applications. The device features a parallel interface for easy connection to microprocessors.

### **Features:**
- **Multirange Inputs:** Software-selectable for flexibility.  
- **Low Power Consumption:** 100mW typical.  
- **Internal/External Clock Options:** Allows timing control.  
- **On-Chip Track/Hold:** Eliminates external circuitry.  
- **No Missing Codes:** Ensures 12-bit accuracy.  
- **Bipolar/Unipolar Input Modes:** Supports various signal types.  
- **Parallel µP Interface:** Simplifies system integration.
