Introduction

The DG418CY+T is a precision analog switch designed for use in a wide variety of switching applications, offering a combination of low on-resistance and high switching speed.

Product Features and Performance

Single Pole Single Throw (SPST) - Normally Open switch configuration

Low on-state resistance of 35 Ohms maximizes signal integrity

Excellent channel-to-channel matching of 3 Ohms or less ensures signal consistency

Compatible with both single and dual supply operations, ranging from 10V to 30V for single supply and ±4.5V to ±20V for dual supply

Fast switching time, with turn-on and turn-off times of 175ns and 145ns respectively

Minimal charge injection of 3pC preserves signal quality

Low channel capacitance of 8pF maintains signal fidelity while switching

Ultra-low leakage current of 250pA minimizes power consumption when off

Product Advantages

The device’s precision and low on-state resistance make it ideal for low distortion signal routing
