Description and Introduction

3.3V, Step-Down, Current-Mode PWM DC-DC Converters The MAX748AEWE+ is a high-performance, dual, 8th-order, lowpass, switched-capacitor filter (SCF) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Dual, 8th-Order Lowpass Switched-Capacitor Filter (SCF)  
- **Package:** 16-pin Wide SOIC (SOIC-16)  
- **Operating Voltage:** ±5V (Dual Supply)  
- **Cutoff Frequency Range:** 0.1Hz to 25kHz (adjustable via external clock)  
- **Clock-to-Cutoff Frequency Ratio:** 100:1 (typical)  
- **Stopband Attenuation:** -80dB (typical)  
- **Total Harmonic Distortion (THD):** -70dB (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX748AEWE+ provides two independent 8th-order lowpass filters in a single IC, offering high precision and low distortion. It is designed for applications requiring sharp roll-off and excellent stopband rejection. The cutoff frequency is set by an external clock, making it highly flexible for different signal processing needs.  

### **Features:**  
- Dual 8th-order lowpass filters in a single package  
- Adjustable cutoff frequency via external clock  
- Low THD (-70dB typical)  
- High stopband attenuation (-80dB typical)  
- Wide operating voltage range (±5V)  
- Low power consumption  
- Suitable for anti-aliasing and reconstruction filtering  

This IC is commonly used in audio processing, telecommunications, and data acquisition systems.
