DG390AAK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG390AAK is a single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two functional blocks within a single channel configuration, utilizing CMOS technology for low power consumption. The device operates with a nominal supply voltage of 15V and supports negative supply rails down to -15V. It is housed in a ceramic dual in-line package (CDIP) with 16 pins, designed for high-reliability applications requiring glass-sealed construction. The component exhibits a maximum on-resistance of 50 ohms and provides typical off-isolation of 62 dB at standard operating conditions.
