MAX4668CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4668CPE+ 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 2.5Ω with guaranteed matching between channels to 0.5Ω max and flatness 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. It offers low off-leakage current of 5nA max at +85°C and handles Rail-to-Rail analog signals. Packaged in a 16-pin Plastic DIP, it operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C, distinct from the industrial 'E' variant. Confirm the 'P' suffix corresponds to the 16-pin Plastic DIP package. Ensure the datasheet revision matches the required specifications for your design. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent analog switching with low distortion is required. The MAX4668 specifically provides two normally open switches, unlike the MAX4667 which offers normally closed configurations. Consider the 2.5Ω on-resistance and leakage characteristics against load requirements. Verify that the operating voltage range aligns with the system's power supply architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4667/MAX4668/MAX4669 family of dual analog switches. The MAX4668 variant is distinguished by its two normally open (NO) contacts, whereas the MAX4667 provides normally closed (NC) contacts and the MAX4669 combines one NC and one NO switch. All variants share identical electrical performance characteristics regarding resistance and speed.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4667CPE+ and MAX4669CPE+. For industrial temperature ranges, consider the MAX4668EPE+ variant. Surface-mount equivalents are available as the MAX4668CSE+ in a 16 Narrow SO package.
