MAX4659EUA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4659EUA+T is a single SPDT CMOS analog switch in an 8-pin µMAX package. It operates on dual supplies from ±4.5V to ±20V or a single supply from +9V to +40V. The device features a maximum on-resistance of 25Ω at ±15V and handles up to 75mA continuous current with a 150mA peak capability. Key electrical parameters include a -3dB bandwidth of 225MHz, off-leakage current of 1nA max, and charge injection of 1.5pC. Operating temperature range spans from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component matches the specific MAX4659 variant rather than the pin-compatible MAX4660, which offers higher continuous current ratings. Confirm the presence of the '+' suffix indicates compliance with RoHS standards. Ensure the 8-pin µMAX package configuration aligns with the target PCB footprint requirements before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high peak current switching is required within a compact surface-mount form factor. The device supports both single and dual supply configurations, offering flexibility for various voltage rails. Consider the 25Ω on-resistance specification against load requirements to ensure acceptable voltage drop during operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4659/MAX4660 family of medium-voltage CMOS analog switches. It serves as a direct replacement for electromechanical relays, providing significantly faster switching speeds and virtually unlimited mechanical life cycles. The series is designed for applications demanding robust current handling in a small footprint.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4660EUA+T is a pin-compatible alternative within the same family that provides higher continuous current handling (150mA vs 75mA). Verify if the increased current capacity is necessary for the specific application load before substituting.
