MAX4603CAE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4603CAE 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 match between channels of 0.5Ω max and flatness of 0.5Ω max over the signal range. It handles rail-to-rail analog signals, offers off-leakage current of 2.5nA max at +85°C, and provides ESD protection exceeding 2000V. TTL/CMOS-compatible inputs ensure logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CAE indicates the commercial temperature range (0°C to +70°C) and SSOP-16 package configuration. Confirm that the ordering code matches the required channel configuration of two normally open and two normally closed switches. Ensure the component source aligns with Analog Devices Inc./Maxim Integrated specifications for quality assurance.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4603CAE when a mixed configuration of normally open and normally closed SPST switches is required within a single package. This part is suitable for applications demanding low distortion and high reliability compared to mechanical relays. Verify that the system voltage requirements fall within the specified single or dual supply ranges for optimal performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4603CAE belongs to the MAX4601/MAX4602/MAX4603 family of quad analog switches. While the MAX4601 features four normally closed switches and the MAX4602 features four normally open switches, the MAX4603 uniquely combines two of each type. All variants share identical electrical characteristics regarding on-resistance, leakage, and switching speeds.
