MAX4601CAE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4601CAE+ is a quad, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a maximum on-resistance of 2.5Ω with guaranteed matching and flatness of 0.5Ω across the signal range. The device supports rail-to-rail analog signal handling and operates from a single supply of +4.5V to +36V or dual supplies of ±4.5V to ±20V. It contains four normally closed switches and offers low off-leakage current of 2.5nA maximum at +85°C. The component is housed in a 16-pin SSOP package and functions within an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CAE+' corresponds to the 16-pin SSOP package and the commercial 0°C to +70°C temperature grade. Confirm that the '+'' indicates RoHS compliance as per manufacturer standards. Ensure the source documentation explicitly lists this part number variant to avoid confusion with the industrial grade 'E' series or alternative packages like Wide SO or Plastic DIP.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4601CAE+ when four normally closed SPST switches are required for low-distortion signal paths. This component is suitable for replacing mechanical relays where board space and reliability are priorities. Verify that the application voltage stays within the +4.5V to +36V single-supply or ±4.5V to ±20V dual-supply limits. Consider the 2.5Ω on-resistance and 2.5nA leakage specifications against system requirements for signal integrity.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4601 belongs to the MAX4601/MAX4602/MAX4603 family of 2.5Ω quad SPST CMOS analog switches. While the MAX4601 provides four normally closed switches, the MAX4602 offers four normally open switches, and the MAX4603 combines two of each. All variants share identical electrical characteristics regarding on-resistance, supply ranges, and package options, differing only in their internal switch configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4602CAE+ (four NO switches) and MAX4603CAE+ (two NO/two NC). For industrial temperature grades (-40°C to +85°C), consider the MAX4601EAE+. Alternative packages such as the 16-Wide SO (MAX4601CWE+) or 16-PDIP (MAX4601CPE+) offer pin-compatible replacements if different form factors are needed.
