Description and Introduction

8th-Order, Lowpass, Switched-Capacitor Filters The MAX291EWE is a low-pass filter manufactured by Maxim Integrated. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** 8th-order, low-pass, switched-capacitor filter  
- **Cutoff Frequency Range:** Adjustable from 0.1Hz to 25kHz  
- **Clock-to-Cutoff Frequency Ratio:** 100:1 (fixed)  
- **Supply Voltage Range:** ±5V (dual supply)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin Wide SOIC (WE)  

### **Descriptions:**  
- The MAX291EWE is a monolithic, 8th-order elliptic low-pass filter with a fixed 100:1 clock-to-cutoff frequency ratio.  
- It is designed for precision signal conditioning in applications requiring steep roll-off and minimal passband ripple.  
- The device operates with a single external clock to set the cutoff frequency.  

### **Features:**  
- **8th-Order Elliptic Response:** Provides sharp roll-off characteristics.  
- **No External Components Required:** Only a clock signal is needed.  
- **Low Noise and Distortion:** Suitable for high-performance filtering.  
- **Wide Adjustable Frequency Range:** Supports cutoff frequencies from 0.1Hz to 25kHz.  
- **Single or Dual Supply Operation:** Compatible with ±5V or +5V supplies.  
- **Low Power Consumption:** Ideal for battery-powered applications.  

This information is based solely on the manufacturer's datasheet for the MAX291EWE.

Application Scenarios & Design Considerations

8th-Order, Lowpass, Switched-Capacitor Filters

Alternative Part Number

  • LTC1069-1CS8 --: Pin-compatible 8th-order lowpass switched-capacitor filter in SO-8, functionally similar to the MAX291 with comparable cutoff frequency range.
  • MF10CCN --: Universal switched-capacitor filter that can be configured as a lowpass filter equivalent to the MAX291, widely available and well documented.
  • TLC14CD --: Fourth-order switched-capacitor lowpass filter in SOIC, suitable as a lower-order substitute where exact order is not critical.
  • LTC1064-1CN --: 8th-order lowpass switched-capacitor filter in DIP, functionally similar to the MAX291 8th-order lowpass filter and usable as a direct design substitute.
