MAX4656ETA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4656ETA+T is a single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices. It features a maximum on-resistance of 10Ω and supports continuous currents up to 300mA with peak capabilities of 400mA. The device operates within a supply range of ±4.5V to ±20V for dual supplies or +9V to +40V for single-supply configurations. It utilizes an 8-pin TDFN package with an exposed paddle, ensuring low power consumption of approximately 3mW. The component provides rail-to-rail signal handling and maintains off-leakage current at a maximum of 1nA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. Ensure the supplier provides official documentation matching the MAX4656ETA+T designation. Confirm RoHS compliance status through the manufacturer's latest release notes before integration into production designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high continuous current handling is required compared to standard analog switches. Consider the TDFN package thermal dissipation characteristics for high-power applications. Verify that the supply voltage range aligns with the system's dual or single supply architecture requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4655–MAX4658 family of medium-voltage CMOS analog switches. It is functionally similar to the MAX4655 but configured as normally open rather than normally closed. The series offers pin compatibility with industry-standard devices like the DG417 and DG418.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG417 and DG418 are listed as pin-compatible alternatives. Verify electrical specifications such as on-resistance and current ratings against the original design requirements before substitution.
