DG444DY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG444DY is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features an on-resistance of 85 ohms maximum and operates within a supply voltage range of +10V to +30V or bipolar ±4.5V to ±20V. The device provides switching times of 250ns maximum for turn-on and 120ns maximum for turn-off. It is housed in a 16-pin Narrow SOIC package with an operating temperature range from -40°C to +85°C.
