Active RC/ 4th Order Lowpass Filter Family The LTC1563-2IGN is a high-performance, low-noise, continuous-time active RC filter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Filter Type:** 8th-order, lowpass elliptic filter  
- **Cutoff Frequency Range:** 10kHz to 150kHz (set by external resistor)  
- **Stopband Attenuation:** ≥72dB  
- **Passband Ripple:** ≤0.1dB  
- **Supply Voltage Range:** ±2.37V to ±5.5V (dual supply) or 4.75V to 11V (single supply)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SSOP  
- **Input Noise Voltage:** 30nV/√Hz (typical)  
- **THD (Total Harmonic Distortion):** < -80dB (for 1Vrms input)  
- **Slew Rate:** 15V/µs (typical)  
- **Gain Bandwidth Product:** 20MHz (typical)  

### **Descriptions:**  
The LTC1563-2IGN is designed for precision signal conditioning in applications requiring high selectivity and low noise. It features a fixed 8th-order elliptic response with steep roll-off and excellent stopband rejection. The cutoff frequency is easily adjustable using an external resistor.  

### **Features:**  
- **Low Noise & Distortion:** Suitable for high-fidelity signal processing.  
- **Wide Supply Range:** Supports both single and dual supplies.  
- **No Clock Required:** Continuous-time operation eliminates clock noise.  
- **Adjustable Cutoff Frequency:** Set via a single external resistor.  
- **High Stopband Rejection:** ≥72dB attenuation.  
- **Small Footprint:** 16-Lead SSOP package for space-constrained designs.  

This filter is ideal for anti-aliasing, communications, medical instrumentation, and audio processing.
