Description and Introduction

8th-Order, Lowpass, Elliptic, Switched-Capacitor Filters The MAX297ESA is a switched-capacitor, 8th-order, lowpass elliptic filter manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Switched-Capacitor Filter  
- **Order:** 8th-order  
- **Filter Type:** Lowpass Elliptic  
- **Clock-to-Cutoff Ratio:** 100:1  
- **Supply Voltage Range:** ±5V (dual supply) or +5V (single supply)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Pin Count:** 8  
- **Cutoff Frequency Range:** Adjustable via external clock (up to 25kHz typical)  
- **Stopband Attenuation:** 72dB min  
- **Passband Ripple:** 0.1dB max  

### **Descriptions:**
- The MAX297ESA is a monolithic, switched-capacitor filter designed for precision signal conditioning.  
- It provides an 8th-order elliptic lowpass response with a sharp roll-off and high stopband rejection.  
- The cutoff frequency is set by an external clock signal, making it highly tunable.  
- Suitable for anti-aliasing, noise reduction, and data acquisition systems.  

### **Features:**
- **Elliptic Response:** Provides steep roll-off and high stopband attenuation.  
- **Adjustable Cutoff Frequency:** Set via an external clock (100:1 clock-to-cutoff ratio).  
- **Single or Dual Supply Operation:** Works with ±5V or +5V supplies.  
- **Low Power Consumption:** Typically 20mW.  
- **No External Components Required:** Minimal external circuitry needed.  
- **High Stopband Rejection:** 72dB minimum attenuation.  
- **Wide Operating Temperature Range:** -40°C to +85°C.  

This information is based solely on the manufacturer's datasheet and technical documentation.
