MAX4605ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4605ESE+T is a CMOS analog switch IC featuring four independent single-pole single-throw (SPST) normally-open channels. It operates within a single supply voltage range of 4.5 V to 36 V or dual supplies of ±4.5 V to ±20 V. The device specifies a maximum on-resistance of 4 ohms and an on-resistance matching between channels of 200 milliohms. Key switching parameters include a maximum turn-on time of 120 ns and a maximum turn-off time of 130 ns. Additional electrical characteristics include a charge injection of 225 pC, off-state leakage current of 500 pA, and crosstalk of -60 dB at 1 MHz. It is housed in a 16-SOIC package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm RoHS compliance and tape-and-reel packaging status. The base part number MAX4605 indicates potential end-of-life status; confirm availability through authorized distributors. Ensure the +T suffix matches the required reel quantity and handling specifications for your assembly line.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-voltage analog switching is required with low distortion. Compare on-resistance stability across temperature ranges if precision is critical. Verify that the 4-ohm resistance meets your signal integrity requirements. Consider the 16-SOIC footprint constraints during PCB layout design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4604/MAX4605/MAX4606 family of high-voltage CMOS analog switches. These parts are designed for applications requiring robust switching performance under varying supply conditions. The MAX4605 variant specifically provides four SPST channels, distinguishing it from dual-channel or multiplexer alternatives in the same series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct pin-compatible replacements such as the MAX4604ESE+T or MAX4606ESE+T if channel count or configuration differences are acceptable. Verify that any substitute maintains the 36 V maximum supply rating and similar on-resistance specifications.
