DG405AK/883B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG405AK/883B is a dual high-speed CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two independent single-pole single-throw (SPST) channels housed in a 16-pin CDIP ceramic package. The device operates on dual power supplies ranging from ±4.5V to ±20V or a single supply up to 30V. Key electrical specifications include a maximum on-resistance of 45 Ohms, an on-time of 150ns, and an off-time of 100ns. It supports a continuous DC current of 20mA per channel with a maximum power dissipation of 696mW.
