DG418AK-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG418AK-E3 is a precision single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features a CMOS logic interface and operates within a supply voltage range of 15 V to 15 V for dual supplies, or 13 V to 44 V for single supplies. The device exhibits a maximum on-resistance of 35 Ohms and supports a DC switch current of 30 mA. Key timing parameters include a maximum turn-on time of 175 ns and a maximum turn-off time of 145 ns. It is housed in an 8-pin CDIP-8 package with a power dissipation rating of 600 mW. The component functions reliably across an extended temperature range from -55°C to +125°C.
