### **Descriptions and Features:**  
- **Lowpass Filtering:** Provides 5th-order elliptic lowpass filtering for precision signal processing.  
- **Adjustable Cutoff Frequency:** The cutoff frequency is set by an external clock signal (100:1 clock-to-cutoff ratio).  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Single or Dual Supply Operation:** Supports both ±5V (dual) and +5V (single) supply configurations.  
- **High Stopband Attenuation:** Features sharp roll-off and high rejection of unwanted frequencies.  
- **No External Components Required:** Minimal external components needed for operation.  
- **Compact PDIP Package:** Easy to integrate into standard PCB designs.  

This IC is commonly used in **audio processing, data acquisition, and communication systems** where precise lowpass filtering is required.
