MAX4541ESA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4541ESA is a dual single-pole/single-throw (SPST) analog switch from the Maxim Integrated MAX4541–MAX4544 family. It operates on a single supply voltage ranging from +2.7V to +12V and features two normally open switches within an 8-pin SO package. The device provides a maximum on-resistance of 60Ω with a typical value of 33Ω at +5V, ensuring low signal attenuation. It supports bidirectional analog signals across the full supply range while maintaining low power consumption of approximately 5µW. The component includes overvoltage protection diodes and guarantees more than 2000V ESD protection per Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'ESA' confirms the industrial temperature range of -40°C to +85°C and the narrow SOIC-8 package format. Confirm that the ordering code matches the exact pinout and electrical specifications required for the target application design. Ensure compatibility with existing PCB footprints before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel SPST switch is required for low-voltage single-supply applications. The MAX4541 variant specifically provides two normally open contacts, distinguishing it from the MAX4542 (normally closed) and MAX4543 (mixed NO/NC). Consider the 60Ω maximum on-resistance limit for signal integrity requirements in the chosen circuit topology.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4541–MAX4544 series of precision, low-voltage analog switches designed by Maxim Integrated. The series differentiates devices based on contact type: MAX4541 offers dual NO, MAX4542 dual NC, MAX4543 mixed NO/NC, and MAX4544 SPDT. All share identical electrical characteristics and pinouts where applicable, allowing for flexible design substitution within the same family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin compatibility with the MAX323, MAX324, and MAX325 series. These legacy parts may serve as functional replacements if available, provided their electrical parameters meet the system requirements.
