MAX4700EWE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4700EWE 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 1.25Ω with guaranteed matching between channels to 0.3Ω and flatness over the signal range. The device operates from +4.5V to +36V single supplies or ±4.5V to ±20V dual supplies, utilizing a separate logic supply pin for TTL/CMOS compatibility. It includes one normally open and one normally closed switch with guaranteed break-before-make switching. The component is housed in a 16-pin Wide SO package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm current availability status as components may be subject to discontinuation. Ensure that any substitute parts maintain identical electrical characteristics and pin configurations to guarantee functional compatibility within the target circuit design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and high precision are required due to its matched on-resistance characteristics. The separate logic supply allows flexible interface options across various voltage domains. Consider the 1.25Ω resistance and leakage specifications relative to the application's signal integrity requirements and power budget constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4680/MAX4690/MAX4700 family of dual SPST analog switches. While sharing similar electrical performance profiles, each variant differs in switch configuration: the MAX4680 provides two normally closed switches, the MAX4690 offers two normally open switches, and the MAX4700 combines one of each with break-before-make functionality.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the MAX4680EWE and MAX4690EWE. These alternatives share the same package and electrical ratings but differ in internal switch polarity. Verify that the specific NO/NC configuration aligns with the existing circuit design before implementation.
