MAX4690EWE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4690EWE+ is a dual single-pole single-throw (SPST) CMOS analog switch featuring a maximum on-resistance of 1.25Ω. It operates from +4.5V to +36V single supplies or ±4.5V to ±20V dual supplies, with TTL/CMOS-compatible logic inputs. The device provides rail-to-rail signal handling and maintains an on-resistance match between channels of 0.3Ω max. Off-leakage current is limited to 5nA max at +85°C. It 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 component against official Analog Devices documentation to confirm pinout alignment and electrical specifications. Ensure the Wide SO package dimensions match the target PCB footprint. Cross-reference the specific suffix to validate the extended industrial temperature rating and lead-free status before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high off-isolation are required for signal routing. Verify that the supply voltage range aligns with the system's power architecture. Consider the thermal dissipation capabilities within the Wide SO package if multiple switches are active simultaneously under load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4680/MAX4690/MAX4700 family of dual analog switches. While sharing similar electrical characteristics, the MAX4690 specifically features two normally open switches, distinguishing it from the MAX4680 (normally closed) and MAX4700 (one NC, one NO).

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include MAX4690CAE, MAX4690CPE, MAX4690EAE, and MAX4690EPE. These variants share identical functionality but differ in temperature ranges and packaging types.
