MAX4680CWE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4680CWE+ 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 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. Electrical characteristics include a maximum off-leakage current of 5nA at +85°C, turn-on time up to 275ns, and turn-off time up to 175ns under dual supply conditions. It provides greater than 2kV ESD protection.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the operating temperature range meets system requirements. Check for RoHS compliance status as indicated in the datasheet. Validate that the logic supply voltage aligns with the host controller interface levels before integration into the design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high channel matching are critical for signal integrity. The wide supply voltage range allows flexibility in power architecture. Consider the 16-Wide SOIC package dimensions for PCB layout constraints. Verify that the leakage current specifications meet the requirements for high-impedance signal paths.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4680/MAX4690/MAX4700 family of dual analog switches. While electrically similar, the MAX4690 offers normally open switches and the MAX4700 combines one normally open and one normally closed switch with break-before-make timing. The MAX4680 specifically provides two normally closed switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4690CWE+ (normally open configuration) and MAX4700CWE+ (mixed NC/NO configuration). These parts share identical pinouts and electrical characteristics but differ in switch state logic.
