MAX4590EAE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4590EAE 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 between channels to 0.25Ω and flatness over the signal range to 0.3Ω. 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. The component is housed in a 16-pin SSOP package and functions within an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'E' confirms the extended industrial temperature range (-40°C to +85°C) and the 'AE' suffix indicates the 16-pin SSOP package format. Confirm RoHS compliance status for the specific manufacturing lot. Ensure logic supply voltage requirements align with system design constraints before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise signal switching are required. The dual SPST NO configuration distinguishes it from the NC MAX4580 and mixed MAX4600 variants. Verify that the 1.25Ω on-resistance meets the application's voltage drop requirements. Consider the 16-SSOP package dimensions for PCB layout compatibility.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4590EAE belongs to the MAX4580/MAX4590/MAX4600 family of 1.25Ω dual analog switches. While electrically similar, the MAX4590 specifically provides two normally open switches, unlike the MAX4580 which has two normally closed switches. This family shares identical electrical characteristics regarding on-resistance, leakage, and power supply ranges.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4590CAE serves as a direct pin-compatible substitute but operates within a commercial temperature range of 0°C to +70°C instead of the industrial range.
