MAX4590CAE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4590CAE+ is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices. 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 rail-to-rail analog signals and operates from +4.5V to +36V single supplies or ±4.5V to ±20V dual supplies. It contains two normally open switches, offers off-leakage current of 2.5nA max at +85°C, and provides ESD protection exceeding 2kV per Method 3015.7. It is housed in a 16-pin SSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component designation against official manufacturer documentation to confirm the specific 'C' temperature grade and 'AE' SSOP package suffix. Ensure that the ordering information aligns with the required operating temperature range of 0°C to +70°C. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin configurations before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise resistance matching are critical for signal integrity. The dual SPST architecture allows independent control of two channels within a compact footprint. Consider the power supply requirements, as it accommodates both single and dual supply rails. Evaluate the thermal dissipation limits relative to the expected continuous current load to ensure reliable operation within the specified temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4580/MAX4590/MAX4600 family of dual analog switches. While sharing identical electrical performance and physical packaging, the MAX4590CAE+ is distinguished by its internal logic configuration featuring two normally open switches. This contrasts with the MAX4580, which utilizes normally closed switches, and the MAX4600, which combines one normally open and one normally closed switch.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4580CAE+ and MAX4600CAE+ offer identical electrical specifications and pinouts but differ in switch state logic. Direct substitution requires verifying that the circuit design accommodates the change from normally open to normally closed or mixed states.
