- **Part Number:** MAX7426CUA  
- **Package:** 8-pin μMAX  
- **Type:** Switched-Capacitor Filter  
- **Operating Voltage Range:** +4.5V to +5.5V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Filter Type:** 5th-order, lowpass  
- **Cutoff Frequency Range:** Adjustable (typically 10Hz to 20kHz)  
- **Supply Current:** 5.5mA (typical)  
- **Stopband Attenuation:** -82dB (typical)  
- **Clock-to-Cutoff Frequency Ratio:** 100:1  

### **Descriptions:**
The MAX7426CUA is a switched-capacitor lowpass filter designed for precision signal conditioning. It provides a 5th-order Butterworth response with minimal passband ripple and high stopband attenuation. The cutoff frequency is set by an external clock, making it flexible for various applications.  

### **Features:**
- **5th-Order Lowpass Filter:** Provides sharp roll-off and high stopband rejection.  
- **Butterworth Response:** Flat passband with minimal ripple.  
- **Adjustable Cutoff Frequency:** Set via an external clock (up to 2MHz).  
- **Low Power Consumption:** Typically 5.5mA at +5V supply.  
- **Single +5V Supply Operation:** Simplifies power requirements.  
- **No External Components Required:** Minimal external circuitry needed.  
- **Small Footprint:** 8-pin μMAX package saves board space.  

This information is based on the manufacturer's datasheet and technical documentation. For exact performance characteristics, refer to the official datasheet.
