### **Descriptions**:
The **TLC04P** is a switched-capacitor filter IC designed for low-pass filtering applications. It provides a 4th-order Butterworth response, which ensures a maximally flat passband. The cutoff frequency is externally adjustable using a clock signal, making it versatile for various signal conditioning needs.
### **Features**:
- **4th-order Butterworth Low-Pass Filter** – Ensures smooth frequency response with minimal ripple in the passband.
- **Adjustable Cutoff Frequency** – Set via an external clock signal (50:1 clock-to-cutoff ratio).
- **Wide Supply Voltage Range** – Operates from 4.5V to 16V, suitable for battery-powered and industrial applications.
- **Low Power Consumption** – Optimized for energy-efficient designs.
- **PDIP Package** – Easy to use in prototyping and through-hole PCB applications.
- **High Input Impedance** – Reduces loading effects on signal sources.
- **Single or Dual Supply Operation** – Compatible with both single-supply and split-supply configurations.
