MAX4659ESA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4659ESA+T is a single SPDT CMOS analog switch in an 8-pin SOIC 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 supplies, with a maximum flatness of 1.5Ω and channel matching of 400mΩ. It supports up to 150mA peak current and 75mA continuous current. Key dynamic parameters include a -3dB bandwidth of 225MHz, charge injection of 1.5pC, and off-leakage current of 1nA max. Operating temperature range is -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix '+T' indicates tape-and-reel packaging when sourcing components. Confirm the 'E' designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the manufacturer is identified as Analog Devices Inc./Maxim Integrated for authenticity. Cross-reference the datasheet revision to ensure compatibility with specific design requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring medium voltage operation up to 40V total supply range. Choose the MAX4659 variant specifically if continuous current requirements do not exceed 75mA. Verify that the 8-pin SOIC package dimensions fit the PCB layout constraints. Consider the exposed paddle connection options if thermal management is critical for the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4659/MAX4660 family of high-current analog switches. The MAX4659 differs from the MAX4660 primarily in its lower continuous current rating (75mA vs 150mA). Both share identical pinouts and electrical characteristics regarding resistance and speed. The family is designed to replace electromechanical relays with solid-state alternatives.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin compatibility with DG419 and MAX319 devices. Verify that substitute parts support the same ±4.5V to ±20V dual-supply range and 25Ω maximum on-resistance specifications.
