### **Descriptions:**  
The MAX7444ESA+ is a monolithic, 5th-order low-pass filter designed for video signal conditioning. It features a Butterworth response for minimal passband ripple and a sharp roll-off. The device includes an input buffer and output driver, making it suitable for video applications requiring signal integrity.  

### **Features:**  
- Integrated input buffer and output driver  
- Adjustable cutoff frequency via external resistor  
- Low group delay variation  
- High stopband rejection (>40dB at 27MHz)  
- Single +5V supply operation  
- Low differential gain/phase error (0.03%/0.03°)  
- Pb-free and RoHS compliant  

This device is commonly used in video processing, broadcast equipment, and other applications requiring precise filtering.
