DG390ABK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG390ABK is a dual single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a low on-state resistance of 50 Ohms and operates with supply voltages ranging from ±5V to ±20V for dual supplies or 10V to 40V for single supplies. The device is housed in a 16-CERDIP package, suitable for surface mount or through-hole applications depending on the specific variant configuration, though the ABK suffix typically denotes a ceramic DIP package. It supports signal switching in multiplexing and interface circuits.
