MAX4690CWE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4690CWE+T is a dual SPST CMOS analog switch in a 16-pin Wide SO package. It features a maximum on-resistance of 1.25Ω with guaranteed matching of 0.3Ω and flatness of 0.3Ω over the signal range. The device supports +4.5V to +36V single-supply or ±4.5V to ±20V dual-supply operation, with TTL/CMOS-compatible logic inputs. Operating temperature ranges from 0°C to +70°C. Key electrical parameters include 5nA maximum off-leakage current at +85°C, 200mA continuous current handling, and >2kV ESD protection.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices. Ensure proper handling procedures are followed due to ESD sensitivity. Validate packaging integrity upon receipt to prevent damage during storage and installation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring low distortion and high reliability compared to mechanical relays. Consider the 16-pin Wide SO package for board space constraints. Verify that the required supply voltage range aligns with the +4.5V to +36V single-supply specification. Ensure thermal management meets the power dissipation limits within the 0°C to +70°C operating range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4680/MAX4690/MAX4700 family of dual analog switches. The MAX4690 variant specifically provides two normally open (NO) switches, distinguishing it from the MAX4680 (normally closed) and MAX4700 (mixed NO/NC). All variants share identical pinouts and core electrical characteristics, facilitating design flexibility across similar system requirements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes within the same family include MAX4680CWE+T and MAX4700CWE+T. These alternatives offer identical footprints and electrical specifications but differ in switch configuration (NC vs. mixed). Verify logic sense compatibility when substituting between these variants.
