Product details

Dual low-Ron analog switch for precision signal routing

The Maxim Integrated MAX4580CWE+ is a dual SPST-NC analog switch in a 16-SOIC surface-mount package. Maximum on-resistance is 1.25 ohm.

Supply range and signal integrity

The 16-SOIC wide-body package (0.295-inch body width, 7.50 mm) is a standard footprint shared by many analog switches and multiplexers. Surface-mount assembly is straightforward — no special thermal pad required, as the 1.25 ohm Ron keeps self-heating low at typical signal currents.

There is no LTB notice or EOL risk on this part.

Frequently asked questions

What is the on-resistance of MAX4580CWE+?

The maximum on-resistance is 1.25 ohm. That's the worst-case value across the full supply range and temperature; typical Ron will be lower at room temperature and nominal supply.

Can I use MAX4580CWE+ with a single 5V supply?

Yes. The single-supply range is 4.5 V to 36 V, so a 5 V rail is within spec. At 5 V, expect the on-resistance to be higher than at higher supply voltages — the 1.25 ohm max is guaranteed across the full supply range, but typical Ron at 5 V will be closer to the upper end.

Can I replace MAX4580CWE+ with MAX4581CWE+?

Yes, if your application needs normally-open (SPST-NO) switches instead of normally-closed. The MAX4581CWE+ is pin-compatible and shares the same package, supply range, and performance specs. The only difference is the switch logic: NC vs NO. For a normally-closed requirement, stick with the MAX4580CWE+.
