8th-Order, Lowpass, Elliptic, Switched-Capacitor Filters The MAX293EWE+T is a precision, 8th-order, lowpass, elliptic, switched-capacitor filter (SCF) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Key Specifications:**  
- **Filter Type:** 8th-order lowpass elliptic  
- **Cutoff Frequency Range:** 0.1Hz to 25kHz (programmable via external clock)  
- **Clock-to-Cutoff Ratio:** 100:1 (typical)  
- **Stopband Attenuation:** 80dB (minimum)  
- **Passband Ripple:** ±0.1dB (typical)  
- **Supply Voltage Range:** ±5V (±2.375V to ±5.5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin Wide SOIC (WE)  

### **Features:**  
- **Low Power Consumption:** 15mA (typical)  
- **No External Components Required** (except clock and power supply)  
- **Pin-Selectable Modes:**  
  - **Clock-Controlled Cutoff Frequency**  
  - **Self-Clocking Mode** (internal oscillator)  
- **High Accuracy:** Tightly controlled cutoff frequency (±0.5% typical)  
- **Low THD (Total Harmonic Distortion):** 0.04% (typical)  

### **Applications:**  
- Anti-aliasing filters  
- Data acquisition systems  
- Audio processing  
- Communication systems  

This device is designed for precision filtering applications requiring high stopband rejection and low passband ripple.
