MAX4733EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4733EUA+ is a low-voltage, dual single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates from a single +2V to +11V supply and handles rail-to-rail analog signals with a maximum on-resistance of 50Ω at +3V and 25Ω at +5V. The device features extremely low leakage current of less than 0.1nA and quiescent power consumption below 0.5nW. It is housed in an 8-pin µMAX package and supports TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EUA+' corresponds to the 8-pin µMAX package variant when sourcing components. Confirm that the temperature range meets the -40°C to +85°C requirement for the intended environment. Ensure the supplier provides documentation confirming RoHS compliance as indicated in the product specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4733EUA+ when a mixed configuration of one normally open and one normally closed SPST switch is required within a dual-channel architecture. This part is appropriate for designs needing rail-to-rail signal integrity with minimal power draw. Consider the 8-pin µMAX package dimensions if board space allows for slightly larger footprints compared to UCSP alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4731/MAX4732/MAX4733 family of low-voltage analog switches. While the MAX4731 offers two normally open switches and the MAX4732 provides two normally closed switches, the MAX4733 uniquely combines one NO and one NC switch. All variants share identical electrical characteristics and packaging options including UCSP, TDFN, and µMAX.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4731EUA+ and MAX4732EUA+ are functionally compatible regarding electrical parameters and package but differ in switch configuration. Direct substitution requires verifying that the circuit design accommodates the change from mixed NO/NC terminals to either all NO or all NC terminals.
