### **Descriptions:**
The MAX274AEWI+ is a monolithic continuous-time active filter that integrates four 2nd-order filter sections, allowing for the implementation of 4th or 8th-order filters. It supports multiple filter responses, including elliptic, Butterworth, and Bessel configurations. The device is designed for precision filtering applications and operates with dual power supplies.

### **Features:**
- **Integrated 4th/8th-Order Filter:** Eliminates the need for external components.  
- **Programmable Filter Response:** Supports elliptic, Butterworth, and Bessel characteristics.  
- **Wide Frequency Range:** Adjustable cutoff frequency up to 150kHz.  
- **Low Power Consumption:** Typically 60mW at ±5V.  
- **Single or Dual Supply Operation:** Compatible with ±4V to ±6V supplies.  
- **No External Clock Required:** Continuous-time operation avoids clock noise.  
- **High Accuracy:** Precision-tuned internal resistors ensure consistent performance.
