MAX4658EUA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4658EUA+T is a single-pole/single-throw (SPST) CMOS analog switch designed for medium-voltage applications. It features a maximum on-resistance of 10Ω and supports continuous current handling up to 150mA with peak currents reaching 300mA. The device operates within a supply voltage range of ±4.5V to ±20V for dual supplies, or +9V to +40V for single-supply configurations. It utilizes an 8-pin µMAX package and maintains an operating temperature range from -40°C to +85°C.

• Audio signal routing and PBX/PABX systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer's marking code against official documentation. Ensure the ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status through the supplier's certification documents before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when high continuous current switching is required alongside low on-resistance. The MAX4658 variant specifically provides a normally open configuration, distinguishing it from the normally closed MAX4657. Consider the thermal dissipation limits of the µMAX package for high-power applications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4655–MAX4658 family of high-current analog switches. The specific MAX4658 model offers a normally open (NO) contact configuration, whereas the MAX4657 provides a normally closed (NC) option. Both share identical electrical characteristics but differ in their default switch state.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet confirms pin compatibility with the DG417 and DG418 devices. Verify that the substitute component supports the same 150mA continuous current rating and 10Ω on-resistance specifications to ensure functional equivalence in existing designs.
