MAX4752EUD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4752EUD+ is a low-voltage, single-supply quad SPST analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +1.6V to +3.6V supply and features four normally closed (NC) switches. The device provides a maximum on-resistance of 0.9Ω at +3V and 2.5Ω at +1.8V. Switching speeds are fast, with turn-on time up to 30ns and turn-off time up to 25ns at +3V. Quiescent power consumption is less than 1µW. It handles continuous currents up to 100mA and supports rail-to-rail analog signals within the supply range.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official Maxim Integrated datasheets for electrical parameters and pin configurations. Confirm that the ordering suffix matches the required package type and temperature range specifications before integration into designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when normally closed logic states are required for the analog switching application. Ensure the design utilizes a single supply between +1.6V and +3.6V. Verify that the 0.9Ω on-resistance meets the signal integrity requirements for the specific load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4751/MAX4752/MAX4753 family of low-voltage analog switches. While electrically similar, the MAX4752 is distinguished by its four normally closed switches, contrasting with the MAX4751's normally open configuration and the MAX4753's mixed state.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4751EUD+ offers identical electrical performance but with four normally open switches instead of normally closed.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the switches in the MAX4752?

The MAX4752 contains four normally closed (NC) switches, meaning they conduct current when the logic input is low.

Can the MAX4752 handle analog signals exceeding the supply voltage?

No, the switches handle rail-to-rail analog signals strictly within the supply voltage range (GND to V+).

Is the MAX4752 suitable for high-speed switching applications?

Yes, it features fast switching speeds with a maximum turn-on time of 30ns and turn-off time of 25ns at a +3V supply.
