DG419DY+TG002

Analog Switches, Multiplexers, Demultiplexers Overview

The DG419DY+TG002 is a single-channel SPDT analog switch manufactured by Analog Devices Inc./Maxim Integrated. It utilizes LC2MOS technology to achieve low on-resistance and ultralow power dissipation. The device operates with a single supply voltage ranging from 10V to 30V or dual supplies of ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 35 ohms, a maximum charge injection of 3pC, and a maximum leakage current of 250pA. Switching times are specified at a maximum of 175ns for turn-on and 145ns for turn-off. The component is housed in an 8-SOIC surface-mount package.
