Description and Introduction

5th-Order, Lowpass, Elliptic, Switched-Capacitor Filters The MAX7426CPA is a switched-capacitor filter manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX7426CPA  
- **Type:** Switched-Capacitor Filter  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage:** +5V ±10%  
- **Filter Type:** 5th-Order, Lowpass  
- **Cutoff Frequency Range:** Programmable from 1Hz to 20kHz  
- **Clock-to-Cutoff Ratio:** 100:1  
- **Stopband Attenuation:** -82dB  
- **Operating Temperature Range:** 0°C to +70°C  
- **Supply Current:** 4.5mA (typical)  

### **Descriptions:**  
The MAX7426CPA is a monolithic, 5th-order, lowpass switched-capacitor filter that provides precise filtering with minimal external components. It is clock-tunable, allowing the cutoff frequency to be adjusted via an external clock signal. The device operates from a single +5V supply and is designed for applications requiring low noise and high stopband attenuation.  

### **Features:**  
- **5th-Order Lowpass Filtering**  
- **Programmable Cutoff Frequency (1Hz to 20kHz)**  
- **Single +5V Supply Operation**  
- **Low Noise and Distortion**  
- **High Stopband Attenuation (-82dB)**  
- **No External Components Required (except clock)**  
- **Pin-Compatible with Industry-Standard MF5 Filter**  

This information is based solely on the manufacturer's datasheet for the MAX7426CPA.

Application Scenarios & Design Considerations

5th-Order, Lowpass, Elliptic, Switched-Capacitor Filters

Alternative Part Number

  • LTC1563-2CN8 --: Pin-compatible 8-pin DIP active filter with similar low-pass response and supply range, from a different series and manufacturer.
  • UAF42AP --: Universal active filter in DIP package offering comparable filter building blocks and wide supply range, a well-known alternative from a different family.
  • MF10CCN --: Switched-capacitor filter in 20-pin DIP with configurable low-pass modes, suitable as a functional substitute when board space allows.
