MAX4657EUA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4657EUA+T is a single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage 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 300mA peak current and 150mA continuous current. It utilizes an 8-pin µMAX package with an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and thermal characteristics. Ensure compatibility with system power supply rails and logic levels before integration. Cross-reference datasheet electrical limits with application requirements to prevent overstress conditions during operation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high continuous current capacity is required alongside low on-resistance. The MAX4657 variant specifically offers lower continuous current ratings compared to the MAX4655, impacting thermal management decisions. Verify that the chosen package provides adequate power dissipation for the intended duty cycle and ambient temperature conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4655–MAX4658 family of medium-voltage CMOS analog switches. The series distinguishes between normally closed (MAX4655/MAX4657) and normally open (MAX4656/MAX4658) configurations. Package variations within the family address different thermal dissipation needs while maintaining identical pinouts and electrical performance profiles.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet confirms pin compatibility with the DG417 and DG418 devices. Verify functional equivalence regarding current ratings and on-resistance flatness before substitution. Ensure that any alternative component meets the specific voltage and current stress requirements defined in the absolute maximum ratings.
