MAX4580EWE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4580EWE is a dual single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin Wide SO package. 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. Operating temperature ranges from -40°C to +85°C. Key electrical parameters include a turn-on time of 160ns, turn-off time of 210ns, off-leakage current of 2.5nA max at +85°C, and charge injection of -60pC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EWE' corresponds to the -40°C to +85°C temperature grade and the 16-Wide SOIC package outline. Confirm that the component is sourced directly from Analog Devices or authorized distributors to ensure authenticity. Check for RoHS compliance status if required by assembly standards.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and high linearity are critical due to its matched on-resistance characteristics. Ensure the application requires dual SPST configuration rather than multiplexing. Verify that the supply voltage constraints fit within the specified single or dual supply ranges for optimal performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4580/MAX4590/MAX4600 family of 1.25Ω dual SPST CMOS analog switches. While the MAX4590 offers normally open switches and the MAX4600 provides mixed NC/NO configurations, the MAX4580 specifically features two normally closed switches. All variants share identical electrical performance metrics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes within the same family include the MAX4590EWE and MAX4600EWE. These alternatives offer different switch states but maintain identical electrical specifications and package dimensions.
