MAX4575EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4575EUA+ is a dual single-pole/single-throw (SPST) CMOS analog switch in an 8-pin µMAX package. It operates on a single supply voltage ranging from +2V to +12V. The device features ±15kV ESD protection on the NO and NC pins, ensuring robustness against electrostatic discharge events without latchup or damage. Key electrical parameters include a maximum on-resistance of 70Ω at +5V and 150Ω at +3V, with typical on-resistance matching of 0.5Ω at +5V. Off-leakage current is guaranteed at 0.5nA at +25°C. The component supports rail-to-rail signal handling, has a -3dB bandwidth exceeding 300MHz, and consumes low power.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SPST CMOS analog switches with integrated ±15kV ESD protection on normally open and normally closed terminals.
• Rail-to-Rail signal range capability allowing operation across the full supply voltage span.
• TTL/CMOS logic compatible control inputs for direct interfacing with standard digital logic families.
• Low distortion characteristics suitable for high-fidelity audio and precision data-acquisition applications.

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-powered systems requiring low power consumption and wide supply voltage flexibility.
• Audio and video signal routing where low distortion and high bandwidth are critical.
• Relay replacement in automated test equipment and applications requiring current switching.
• Low-voltage data-acquisition systems and sample-and-hold circuits.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EUA+' corresponds to the 8-pin µMAX package and the -40°C to +85°C industrial temperature range as listed in the ordering information. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design margins account for the absolute maximum ratings, particularly regarding continuous current limits and power dissipation derating above +70°C.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4575 variant specifically when two normally open switches are required, distinguishing it from the MAX4576 (two NC) and MAX4577 (one NO, one NC). Evaluate on-resistance flatness requirements, as the device exhibits typical flatness of 2Ω at +5V. Consider the break-before-make timing if utilizing the MAX4577 configuration for seamless signal transfer between sources.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4575/MAX4576/MAX4577 family of low-voltage, high ESD-protected analog switches manufactured by Analog Devices / Maxim Integrated. These devices are designed as pin-compatible replacements for mechanical relays in space-constrained designs. The family shares identical pinouts and core specifications, differing only in the internal connection of the switches (NO, NC, or mixed).

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states pin compatibility with the MAX4541, MAX4542, and MAX4543 series. Designers replacing legacy components should verify that the substitute part meets the same ESD protection levels and on-resistance specifications for the target application environment.
