DG417LEUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG417LEUA+ is a precision, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a maximum on-resistance of 35Ω and operates within an extended temperature range of -40°C to +85°C. The device supports single-supply voltages from +9V to +36V or dual supplies ranging from ±4.5V to ±20V. It incorporates +3V logic-compatible digital inputs with defined thresholds of 0.8V for logic-low and 2.0V for logic-high. The component is housed in an 8-pin µMAX package.
