Descriptions:

The DG418CY+T is a precision, low-leakage analog switch designed for high-voltage applications. It features low on-resistance, fast switching speeds, and minimal charge injection, making it suitable for signal routing in data acquisition, audio switching, and communication systems.

Features:

• Low On-Resistance: Ensures minimal signal distortion.
• Wide Voltage Range: Supports both single and dual power supplies.
• Fast Switching: Enables high-speed signal routing.
• Low Charge Injection: Reduces errors in precision applications.
• High Off-Isolation: Minimizes signal leakage when switched off.
• TTL/CMOS Compatible Logic Inputs: Easy interfacing with digital control circuits.
• ESD Protection: Robust against electrostatic discharge.

This switch is commonly used in multiplexers, sample-and-hold circuits, and battery-powered systems.
