MAX4605CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4605CSE+T is a quad single-pole single-throw (SPST) CMOS analog switch featuring four normally open channels. It operates from a single supply of +4.5V to +36V or dual supplies of ±4.5V to ±20V. The device guarantees a maximum on-resistance of 5Ω with a channel-to-channel match of 0.5Ω and flatness of 0.5Ω over the signal range. Electrical specifications include a turn-on time of 120ns, turn-off time of 130ns, off-leakage current of 0.5nA max at +85°C, and charge injection of 225pC. It is housed in a 16-pin Narrow SO package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official Analog Devices documentation to confirm authenticity. Ensure the ordering suffix matches the required temperature grade and packaging format. Cross-reference pin configurations and electrical limits with the datasheet before integration into designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring normally open switching with low distortion. Verify that the system power supply falls within the specified single or dual voltage ranges. Confirm that the thermal dissipation requirements are met by the 16-pin Narrow SO package constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4604/MAX4605/MAX4606 family of quad analog switches. The MAX4605 variant specifically provides four normally open switches, distinguishing it from the MAX4604 (normally closed) and MAX4606 (mixed configuration). All variants share identical electrical characteristics and pinouts.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4605 and MAX4604?

The MAX4605 contains four normally open (NO) switches, whereas the MAX4604 contains four normally closed (NC) switches. Both share the same electrical specifications and pinout.

How does the MAX4605 handle overvoltage conditions?

Signals on the switch pins exceeding V+ or V- are clamped by internal diodes. External blocking diodes may be added if proper power-supply sequencing cannot be guaranteed.

Is the MAX4605 suitable for high-frequency applications above 5MHz?

While the switch extends to above 100MHz in 50Ω systems, circuit board layout becomes critical above 5MHz. For critical RF applications, specialized parts like the MAX440 series are recommended.
