MAX4608CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4608CSE+T is a dual 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 channel matching and flatness both limited to 0.5Ω max over 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 includes TTL/CMOS-compatible control inputs and offers off-leakage current of 2.5nA max at +85°C. The component is housed in a 16-pin Narrow SO 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 against official documentation to confirm lead-free status and RoHS compliance. Ensure the narrow SOIC package type matches the design footprint requirements. Confirm that the commercial temperature grade meets the environmental constraints of the target application before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high channel matching are critical for signal integrity. Verify that the required voltage range falls within the specified single or dual supply limits. Consider the package size and thermal dissipation characteristics relative to the board layout constraints and ambient operating conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4607/MAX4608/MAX4609 family of dual SPST CMOS analog switches. While sharing core electrical characteristics, the MAX4608 specifically provides two normally open switches, distinguishing it from the MAX4607 which offers normally closed configurations. This configuration choice dictates the default state of the analog paths upon power-up.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional replacements within the same family include the MAX4607CSE+T and MAX4609CSE+T, provided the specific switch configuration aligns with the circuit design. Cross-family substitutes require verification of pinout compatibility and electrical parameter alignment.
