5th Order, Lowpass, Elliptic, Switched-Capacitor Filters The MAX7408EUA+T is a low-power, 8th-order, lowpass, switched-capacitor filter manufactured by Maxim Integrated.  

### **Specifications:**  
- **Filter Type:** 8th-order, lowpass  
- **Architecture:** Switched-capacitor  
- **Cutoff Frequency Range:** 1Hz to 15kHz (adjustable via external clock)  
- **Clock-to-Cutoff Frequency Ratio:** 100:1  
- **Supply Voltage Range:** ±5V or +5V  
- **Operating Current:** 1.5mA (typical)  
- **Stopband Attenuation:** -80dB (typical)  
- **Passband Ripple:** ±0.1dB (typical)  
- **Package:** 8-pin µMAX (UA)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions and Features:**  
- **Low-Power Operation:** Consumes only 1.5mA (typical) for efficient filtering.  
- **Precision Filtering:** Provides 8th-order elliptic response for sharp roll-off.  
- **Adjustable Cutoff Frequency:** Set via an external clock signal (1Hz to 15kHz range).  
- **Single or Dual Supply Operation:** Works with ±5V or +5V supplies.  
- **High Stopband Attenuation:** -80dB rejection for unwanted frequencies.  
- **Small Footprint:** 8-pin µMAX package for space-constrained applications.  
- **No External Components Required:** Minimal external circuitry needed for operation.  

This device is commonly used in audio processing, communications, and signal conditioning applications requiring precise lowpass filtering.
