MAX4658ESA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4658ESA+ is a single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply range of ±4.5V to ±20V for dual supplies or +9V to +40V for single supplies, supporting rail-to-rail signal handling. The device features a maximum on-resistance of 10Ω at ±15V supplies and handles up to 300mA continuous current with a 400mA peak capability. Key electrical parameters include a turn-on time of 200ns maximum, turn-off time of 100ns maximum, off-leakage current of 1nA maximum, and a -3dB bandwidth of 210MHz. It is housed in an 8-pin SO package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure that any pin-compatible alternatives maintain identical electrical characteristics and pinout configurations. Cross-reference manufacturer datasheets for updated availability status and environmental compliance details prior to finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high current switching is required alongside low on-resistance. Verify that the application voltage does not exceed the absolute maximum ratings for the chosen supply configuration. Consider thermal management requirements based on the specific package power dissipation limits and ambient operating conditions defined in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4655–MAX4658 family of medium-voltage CMOS analog switches. While electrically similar to other members, the MAX4658 is distinguished as a normally open (NO) variant with specific continuous current ratings of 150mA and peak ratings of 300mA. It shares pin compatibility with legacy devices like the DG418 but offers improved current handling capabilities.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4658 is pin-compatible with the DG418. Verify that substitute components match the SPST configuration, current ratings, and package dimensions. Ensure that alternative parts support the required supply voltage range and meet the necessary TTL/CMOS logic level thresholds for proper operation.
