DG419AK/883B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG419AK/883B is a single-channel, single-pole double-throw (SPDT) CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a dual supply voltage range of ±4.5V to ±20V or a single supply of 9V to 36V. The device features a maximum on-state resistance of 35 ohms and low charge injection of 15pC. It is housed in an 8-pin plastic dual in-line package (PDIP). Key electrical parameters include a maximum off-state leakage current of 250pA and a channel-to-channel matching of 100 milliohms.
