Description and Introduction

Clock-Tunable, Quad Second Order, Filter Building Blocks The LTC1068-25CG is a high-performance, low-power, switched capacitor filter manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Linear Technology (LTC)  
- **Part Number:** LTC1068-25CG  
- **Package:** 28-Lead SSOP (CG Package)  
- **Operating Temperature Range:** 0°C to 70°C (Commercial Grade)  
- **Supply Voltage Range:** ±2.5V to ±8V (Dual Supply) or 5V to 16V (Single Supply)  
- **Power Consumption:** 5mA (Typical) at ±5V Supply  
- **Filter Type:** 8th Order, Lowpass, Elliptic Response  
- **Cutoff Frequency Range:** Programmable up to 150kHz  
- **Stopband Attenuation:** 72dB (Minimum)  
- **Passband Ripple:** 0.1dB (Typical)  
- **Clock-to-Cutoff Frequency Ratio:** 50:1 (Fixed)  

### **Descriptions:**  
- The LTC1068-25CG is a precision, 8th-order, lowpass switched capacitor filter with a fixed 50:1 clock-to-cutoff frequency ratio.  
- It features an elliptic response for steep roll-off and high stopband rejection.  
- Designed for low-power operation, making it suitable for battery-powered applications.  
- Includes an internal clock oscillator (optional external clock input available).  

### **Features:**  
- **Low Power Consumption:** Ideal for portable and battery-operated systems.  
- **No External Components Required:** Minimal external circuitry needed for operation.  
- **Single or Dual Supply Operation:** Supports flexible power configurations.  
- **High Stopband Rejection:** 72dB minimum attenuation ensures effective noise filtering.  
- **Low Sensitivity to Clock Duty Cycle:** Ensures stable performance.  
- **Pin-Programmable Cutoff Frequency:** Adjustable via external resistor or clock input.
