MAX4668EPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4668EPE+ is a dual SPST CMOS analog switch in a 16-pin Plastic DIP package. It features a maximum on-resistance of 2.5Ω with a channel-to-channel match of 0.4Ω and flatness of 0.5Ω. The device supports single supplies from +4.5V to +36V or dual supplies from ±4.5V to ±20V. Key electrical parameters include a maximum off-leakage current of 5nA at +85°C, turn-on time of 400ns (typical), and turn-off time of 300ns (typical). It operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against the official Maxim Integrated datasheet specifications before integration. Confirm that the 16-PDIP package dimensions align with the target PCB footprint. Ensure the operating environment remains within the specified -40°C to +85°C temperature range to maintain guaranteed performance levels.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when low distortion and high linearity are required due to its matched on-resistance characteristics. Consider the MAX4667 if normally closed switches are needed instead of the normally open configuration found in the MAX4668. Evaluate the MAX4669 if break-before-make timing is critical for the specific application design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4667/MAX4668/MAX4669 family of dual analog switches. While sharing similar electrical characteristics and pinouts, the MAX4668 specifically provides two normally open switches. This distinguishes it from the MAX4667 (normally closed) and MAX4669 (mixed NC/NO) variants within the same series.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4668 and MAX4667?

The MAX4668 contains two normally open (NO) switches, whereas the MAX4667 contains two normally closed (NC) switches. Both share identical electrical specifications and pin configurations.

How does the on-resistance behave over the signal range?

The on-resistance is guaranteed to be flat with a maximum variation of 0.5Ω over the specified signal range, ensuring low distortion in analog signal paths.
