Description and Introduction

4th- and 8th-Order, Continuous-Time Active Filters The MAX275AEWP+ is a continuous-time active filter manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Continuous-Time Active Filter  
- **Operating Supply Voltage:** ±2.37V to ±5.5V (Dual Supply)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin Wide SOIC (SOIC-20)  
- **Filter Type:** 4th-Order or Dual 2nd-Order Butterworth, Bessel, or Chebyshev  
- **Center Frequency Range:** 10kHz to 150kHz (adjustable via external resistors)  
- **Gain Range:** Programmable (via external resistors)  
- **Power Supply Current:** 8mA (typical) per filter section  

### **Descriptions:**
The MAX275AEWP+ integrates two independent 2nd-order filter sections, allowing the configuration of a 4th-order filter or dual 2nd-order filters. It operates without requiring external clocks or switched-capacitor components, making it ideal for noise-sensitive applications. The filter characteristics (Butterworth, Bessel, or Chebyshev) are determined by external resistor selections.

### **Features:**
- **No External Clock Required:** Eliminates switching noise.  
- **Wide Frequency Range:** Adjustable from 10kHz to 150kHz.  
- **Low Distortion:** Ensures high signal fidelity.  
- **Low Noise:** Suitable for precision analog applications.  
- **Flexible Configuration:** Supports 4th-order or dual 2nd-order filters.  
- **Single or Dual Supply Operation:** Compatible with ±2.37V to ±5.5V supplies.  
- **Low Power Consumption:** 8mA per filter section (typical).  

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

Application Scenarios & Design Considerations

4th- and 8th-Order, Continuous-Time Active Filters

Alternative Part Number

  • LTC1068CG --: Quad universal switched-capacitor filter with similar continuous-time filter building block function; widely available and pin-configurable for comparable active filter designs.
  • MF10CCN --: Classic dual switched-capacitor filter that can implement similar continuous-time filter responses; good functional substitute for filter design work.
  • UAF42AP --: Universal active filter building block offering low-pass, high-pass, band-pass and notch configurations, suitable as an alternative for analog filter applications.
  • LTC1068CG#PBF --: Quad universal switched-capacitor filter in a 20-pin SOIC package, functionally comparable to the MAX275 continuous-time filter for signal filtering applications.
