MAX4590CWE is listed in the Analog Switches, Multiplexers, Demultiplexers range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is IC SW SPST-NOX2 1.25OHM 16SOIC. Review the specifications below when checking this part for your BOM.
The MAX4590CWE is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a maximum on-resistance of 1.25Ω with guaranteed matching of 0.25Ω and flatness of 0.3Ω over the signal range. The device supports +4.5V to +36V single supplies or ±4.5V to ±20V dual supplies, handling rail-to-rail analog signals. It operates within a commercial temperature range of 0°C to +70°C and is housed in a 16-pin Wide SO package.
Verify the specific suffix 'C' indicates the commercial temperature grade (0°C to +70°C) and 'WE' denotes the 16-pin Wide SOIC package. Confirm that the component is lead-free and RoHS compliant as per standard manufacturer specifications for this part number series before finalizing procurement orders.
Select the MAX4590 variant specifically for applications requiring two normally open channels. Ensure the system voltage requirements align with the specified single or dual supply ranges. Consider the 16-pin Wide SO package dimensions for PCB layout constraints compared to SSOP or DIP alternatives.
This component belongs to the MAX4580/MAX4590/MAX4600 family of low on-resistance analog switches. While electrically similar, the MAX4590 is distinguished by its dual normally open configuration, contrasting with the MAX4580's dual normally closed design and the MAX4600's mixed NC/NO arrangement.
Direct pin-compatible substitutes include the MAX4590CAE (SSOP package) and MAX4590CPE (Plastic DIP package). Verify package footprint compatibility when transitioning between these variants.
