MAX4658ESA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4658ESA+T is a single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. It operates within a supply range of ±4.5V to ±20V for dual supplies or +9V to +40V for single-supply configurations. The device features a maximum on-resistance of 10Ω at ±15V supplies and supports up to 150mA continuous current and 300mA peak current. It handles rail-to-rail analog signals with an off-leakage current of 1nA maximum at +25°C. The component operates over a temperature range of -40°C to +85°C and is housed in an 8-pin SO package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• High-current handling capability supporting up to 150mA continuous and 300mA peak load currents
• Low on-resistance of 10Ω maximum with flatness under 1Ω across the specified signal range
• Rail-to-rail signal handling allowing operation from any combination of supplies within the 40V differential limit
• TTL/CMOS compatible logic control eliminating the need for level shifting

Analog Switches, Multiplexers, Demultiplexers Applications

• Relay replacement in systems requiring high speed and unlimited lifetime cycles
• Audio signal routing and audio system interconnects
• Test equipment and redundant backup switching architectures

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'ESA' corresponds to the 8-pin SOIC package and the '+T' indicates tape-and-reel packaging. Confirm that the ordering information matches the manufacturer's current datasheet revision, as package options may vary between SO, µMAX, and TDFN formats. Ensure compatibility with the required thermal dissipation limits for the selected enclosure type during integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4658 variant specifically for normally open (NO) circuit configurations, distinguishing it from the normally closed MAX4657. Evaluate power dissipation requirements against the SO package derating curves, particularly when operating near the maximum voltage differentials. Consider the 10Ω on-resistance variation with temperature and supply voltage when designing precision analog signal paths.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4655–MAX4658 family of high-current CMOS analog switches. The series shares identical electrical characteristics regarding current handling and resistance, differentiated primarily by their default switch states (normally open vs. normally closed) and available package styles. The MAX4658 represents the normally open configuration within this high-performance switching group.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet identifies the DG417 and DG418 as pin-compatible alternatives. Verify that substitute components meet the specific 150mA continuous current requirement and 10Ω on-resistance specifications before implementation.
