MAX4690CWE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4690CWE+ is a dual SPST CMOS analog switch in a 16-pin Wide SOIC package. It features a maximum on-resistance of 1.25Ω with guaranteed matching to 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, ensuring TTL/CMOS logic compatibility via a separate VL pin. Operating temperature range is 0°C to +70°C. Key electrical parameters include off-leakage current of 5nA max at +85°C, charge injection of 550pC, and turn-on/off times up to 275ns/175ns under dual supplies.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Rail-to-Rail signal handling capability for low-distortion applications
• Guaranteed break-before-make switching not applicable (MAX4690 is NO only)
• TTL/CMOS-compatible control inputs independent of analog supply voltage

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Data acquisition systems requiring current switching
• Sample-and-hold circuits
• Communication systems and PBX/PABX networks

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the suffix 'CWE' corresponds to the 0°C to +70°C commercial temperature grade and 16-Wide SOIC package. Confirm RoHS compliance status through official manufacturer documentation. Check for obsolescence notices as Maxim Integrated products may have lifecycle changes. Ensure logic supply sequencing follows recommended power-up procedures to prevent latch-up.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high channel matching are critical for signal integrity. The MAX4690 provides two normally open switches; choose MAX4680 for normally closed or MAX4700 if break-before-make timing is required. Verify that the single-supply voltage range (+4.5V to +36V) aligns with system power rails. Consider thermal dissipation limits in the Wide SOIC package for high-current applications.

Analog Switches, Multiplexers, Demultiplexers Part Context

Part of the MAX4680/MAX4690/MAX4700 family of dual analog switches from Analog Devices/Maxim Integrated. Shares identical pinout and core specifications with MAX4680 and MAX4700, differing primarily in switch configuration (NC, NO, or mixed). Designed as a solid-state alternative to mechanical relays, offering higher reliability and smaller board space.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include MAX4690EWE+ (extended temperature -40°C to +85°C) and MAX4690CAE+/MAX4690EAE+ (SSOP package). Cross-family replacements require verification of on-resistance, leakage, and package dimensions. No other manufacturers offer pin-compatible equivalents with identical 1.25Ω RON specs.
