- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 28-pin wide SOIC (MAX198ACWI)  

### **Descriptions:**  
The MAX198ACWI integrates an 8-channel multiplexer, high-bandwidth track/hold, and a 12-bit successive-approximation ADC. It is designed for precision data acquisition in industrial and instrumentation applications. The device features software-selectable input ranges, allowing flexible interfacing with various sensor types.  

### **Features:**  
- **Multirange Inputs:** Supports ±10V, ±5V, 0 to +10V, and 0 to +5V ranges.  
- **Low Power:** 100mW typical power consumption.  
- **Internal/External Clock:** Configurable for internal or external clock operation.  
- **Parallel Interface:** Easy interfacing with microprocessors.  
- **On-Chip Track/Hold:** Eliminates the need for external circuitry.  
- **Software-Configurable:** Input ranges and channel selection via digital control.  

This device is ideal for applications requiring high-speed, multichannel data acquisition with flexible input ranges.
