Description and Introduction

5th-Order, Lowpass, Switched-Capacitor Filters The MAX7419EUA+T is a fifth-order, lowpass, switched-capacitor filter (SCF) manufactured by Maxim Integrated.  

### **Specifications:**  
- **Filter Type:** Lowpass  
- **Filter Order:** 5th-order  
- **Cutoff Frequency Range:** 1Hz to 15kHz  
- **Supply Voltage Range:** ±2.375V to ±5.5V (dual supply), +4.75V to +11V (single supply)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin μMAX (MSOP)  
- **Clock-to-Cutoff Frequency Ratio:** 100:1  
- **THD (Total Harmonic Distortion):** 0.05% (typical)  
- **Signal-to-Noise Ratio (SNR):** 80dB (typical)  
- **Power Consumption:** 5.5mA (typical, ±5V supply)  

### **Descriptions:**  
The MAX7419EUA+T is a monolithic, fifth-order, lowpass filter designed for precision signal processing. It uses a switched-capacitor architecture to provide accurate frequency response without requiring external components for tuning. The filter is clock-tunable, allowing the cutoff frequency to be adjusted via an external clock signal.  

### **Features:**  
- **No External Components Required** for filter response  
- **Pin-Selectable Clock Modes** (Self-clocking or external clock)  
- **Low THD and High SNR** for clean signal processing  
- **Wide Supply Voltage Range** supports single or dual supplies  
- **Low Power Consumption** for portable applications  
- **Small Footprint** (8-pin μMAX package)  

This device is commonly used in anti-aliasing, data acquisition, and audio signal processing applications.

Application Scenarios & Design Considerations

5th-Order, Lowpass, Switched-Capacitor Filters

Alternative Part Number

  • LTC1562CGN#PBF --: Active RC lowpass filter with similar 5th-order response and cutoff range, pin-compatible function in a different series.
  • AD8620ARZ --: Low-noise op-amp usable to build equivalent active filter stages, widely available and electrically robust.
  • TLV2374IDR --: Quad rail-to-rail op-amp suitable for implementing the same filter topology at lower cost.
