MAX4602EWE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4602EWE+ is a quad single-pole single-throw (SPST) normally open CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply of +4.5V to +36V or dual supplies of ±4.5V to ±20V. The device features a maximum on-resistance of 2.5Ω, with guaranteed on-resistance matching between channels of 0.5Ω max and flatness of 0.5Ω max over the specified signal range. Digital inputs have logic thresholds of +0.8V and +2.4V, ensuring TTL/CMOS compatibility. It handles rail-to-rail analog signals with an off-leakage current of 2.5nA maximum at +85°C. The component is housed in a 16-Wide SOIC package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EWE+' against the manufacturer's official datasheet to confirm the extended temperature range (-40°C to +85°C) and the 16-pin Wide SOIC package configuration. Ensure that the ordering documentation explicitly references the MAX4602 family specifications regarding on-resistance and leakage currents before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when replacing mechanical relays in applications requiring low power consumption and reduced board space. The device is suitable for circuits demanding rail-to-rail signal swing and precise on-resistance matching. Verify that the application logic levels align with the specified +0.8V and +2.4V input thresholds for reliable operation under single or dual supply conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4601/MAX4602/MAX4603 family of quad analog switches. While the MAX4601 offers normally closed switches and the MAX4603 provides a mixed configuration, the MAX4602 specifically contains four normally open switches. All variants share identical electrical characteristics regarding on-resistance, leakage, and supply voltage ranges within their respective temperature grades.
