MAX4503EUK

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4503EUK is a low-voltage, dual-supply, single-pole/single-throw (SPST) CMOS analog switch housed in a 5-pin SOT23-5 package. It features a normally open configuration and operates with dual supplies ranging from ±1V to ±6V. The device handles rail-to-rail analog signals with an on-resistance of up to 250Ω at ±5V supplies. Key electrical parameters include off-leakage current of 1nA at +25°C and turn-on/turn-off times of 150ns and 100ns respectively. It supports a maximum continuous current of ±10mA into any terminal.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual-supply operation capability spanning ±1V to ±6V for flexible power configurations
• Normally open (NO) SPST architecture ensuring default signal path isolation
• CMOS-logic compatible input interface without requiring a dedicated ground pin
• Rail-to-rail analog signal handling across the full supply voltage range

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-operated equipment requiring low power consumption
• Audio and video signal routing systems
• Low-voltage data-acquisition systems
• Communications circuits and cellular phones
• PCMCIA cards and modems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EUK confirms the -40°C to +85°C industrial temperature grade and SOT23-5 surface-mount packaging. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4503EUK when a normally open switch state is required for dual-supply applications. Ensure the system logic levels are compatible with the internal V+ referenced translator. For single-supply designs, consider the MAX4501/MAX4502 as pin-for-pin equivalents instead.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4503/MAX4504 family of low-voltage CMOS analog switches. The MAX4503 variant specifically provides a normally open configuration, whereas the MAX4504 offers a normally closed state. Both share identical electrical characteristics and package options within the series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4502 serves as a pin-for-pin equivalent for single-supply operations. Verify that replacement parts maintain the same SOT23-5 footprint and meet the required ±1V to ±6V dual-supply operating range.
