Description and Introduction

8th-Order, Lowpass, Elliptic, Switched-Capacitor Filters The MAX7400ESA+T is a low-power, 5th-order, lowpass switched-capacitor filter manufactured by Maxim Integrated. Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Filter Type:** 5th-order, lowpass  
- **Architecture:** Switched-capacitor  
- **Cutoff Frequency Range:** 1Hz to 25kHz  
- **Supply Voltage Range:** ±2.5V to ±5.5V (dual supply), +5V to +11V (single supply)  
- **Power Consumption:** 2.5mA (typical) at ±5V  
- **Stopband Attenuation:** -60dB (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (ESA)  

### **Descriptions:**  
The MAX7400ESA+T is a monolithic, low-power, 5th-order lowpass filter with a Butterworth response. It uses a switched-capacitor architecture for precise frequency control without external components. It is ideal for anti-aliasing, noise reduction, and signal conditioning in data acquisition and audio applications.  

### **Features:**  
- **Low Power Consumption:** 2.5mA typical at ±5V  
- **No External Components Required:** Internal clock sets cutoff frequency  
- **Wide Frequency Range:** Adjustable from 1Hz to 25kHz  
- **Single or Dual Supply Operation:** Supports ±2.5V to ±5.5V or +5V to +11V  
- **High Stopband Attenuation:** -60dB typical  
- **Low Noise and Distortion:** Suitable for precision applications  
- **Compact Package:** 8-pin SOIC for space-constrained designs  

This information is based strictly on the manufacturer's datasheet.

Application Scenarios & Design Considerations

8th-Order, Lowpass, Elliptic, Switched-Capacitor Filters

Alternative Part Number

  • LTC1068CG#PBF --: Pin-compatible switched-capacitor filter family from Linear Technology (now ADI) with similar 8th-order lowpass response and supply range, widely used as a MAX7400 substitute.
  • MF10CCN --: Classic universal switched-capacitor filter that can be configured as an 8th-order lowpass, offering a flexible alternative when the exact MAX7400 response is not mandatory.
  • UAF42AP --: Universal active filter IC that can implement lowpass responses up to the same order, suitable as a functional replacement in filter designs where a switched-capacitor part is not strictly required.
