### **Descriptions:**
The MAX297EWE+ is an 8th-order, lowpass, switched-capacitor filter designed for precision signal conditioning. It provides a sharp roll-off and high stopband rejection, making it suitable for anti-aliasing and noise reduction in data acquisition systems. The cutoff frequency is set by an external clock signal, allowing flexible tuning.
### **Features:**
- **Elliptic Filter Response** – Provides steep roll-off and high stopband attenuation.
- **Adjustable Cutoff Frequency** – Set via an external clock (fCLK/100).
- **Low Power Consumption** – Typically 50mW.
- **Single +5V or Dual ±5V Operation** – Supports both single and dual supply configurations.
- **Low Passband Ripple** – 0.1dB typical for accurate signal integrity.
- **Wide Operating Temperature Range** – -40°C to +85°C.
- **Surface-Mount Package** – 16-pin Wide SOIC for compact designs.
