MAX4603EAE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4603EAE is a quad, single-pole/single-throw (SPST) CMOS analog switch featuring two normally open and two normally closed channels. It operates from a single supply of +4.5V to +36V or dual supplies of ±4.5V to ±20V. The device guarantees a maximum on-resistance of 2.5Ω with a channel-to-channel match of 0.5Ω max and flatness of 0.5Ω max over the signal range. Electrical characteristics include a turn-on time of 160ns, turn-off time of 170ns, charge injection of 20pC, and off-leakage current of 1nA at +85°C. It is housed in a 16-pin SSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EAE' corresponds to the -40°C to +85°C temperature range and 16-pin SSOP package configuration. Confirm RoHS compliance status for the exact revision being procured. Ensure logic thresholds align with the system's TTL/CMOS voltage levels when using ±15V or single +12V supplies.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring mixed normally open and normally closed switches within a single package. The low on-resistance and high matching accuracy make it suitable for precision signal routing. Verify that the 16-pin SSOP footprint fits the PCB layout constraints and that the operating temperature range meets environmental requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4603 is part of the MAX4601/MAX4602/MAX4603 family of 2.5Ω quad SPST CMOS analog switches. While the MAX4601 offers four normally closed switches and the MAX4602 provides four normally open switches, the MAX4603 uniquely combines two of each type. This family serves as a solid-state alternative to mechanical relays in automatic test equipment and audio routing systems.
