Description and Introduction

8th-Order, Lowpass, Elliptic, Switched-Capacitor Filters The MAX294CWE is a switched-capacitor, 8th-order, lowpass filter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
- **MAX** (Maxim Integrated, now Analog Devices)  

### **Specifications:**  
- **Order:** 8th-order lowpass filter  
- **Filter Type:** Switched-capacitor  
- **Cutoff Frequency Range:** Adjustable from **0.1Hz to 25kHz** (set by an external clock)  
- **Clock-to-Cutoff Ratio:** **100:1** (typical)  
- **Supply Voltage Range:** **±5V** (dual supply) or **+5V to +12V** (single supply)  
- **Operating Temperature Range:** **0°C to +70°C**  
- **Package:** **16-pin Wide SOIC (CWE)**  

### **Descriptions:**  
- The MAX294CWE is a monolithic, 8th-order, elliptic lowpass filter with a switched-capacitor architecture.  
- It provides precise filtering with minimal external components.  
- The cutoff frequency is programmable via an external clock signal.  
- Suitable for anti-aliasing, noise reduction, and signal conditioning in data acquisition systems.  

### **Features:**  
- **Elliptic Response:** Sharp roll-off with minimal passband ripple.  
- **Low Power Consumption:** Typically **10mA** supply current.  
- **No External Components Required:** Only a clock signal is needed to set the cutoff frequency.  
- **High Accuracy:** Cutoff frequency determined by clock frequency (100:1 ratio).  
- **Single or Dual Supply Operation:** Supports both configurations.  
- **Low THD (Total Harmonic Distortion):** Typically **0.2%** at 1kHz.  
- **Stopband Attenuation:** **80dB** (typical).  

This information is based solely on the manufacturer's datasheet and technical documentation.
