MAX4590CAE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4590CAE+ 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 includes TTL/CMOS-compatible control inputs, low off-leakage current of 2.5nA max at +85°C, and 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 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm pin-package type and temperature range. Ensure that any additional characters in the part number do not indicate variations in function or packaging format unless explicitly documented. Cross-reference the manufacturer part number with authorized distributor listings to confirm current availability status and compliance with relevant environmental standards such as RoHS.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise resistance matching are required for analog signal switching. The dual SPST architecture allows for independent control of two signal paths. Consider the 1.25Ω on-resistance and rail-to-rail operation for applications requiring minimal signal attenuation and wide voltage swing handling without external biasing adjustments.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4590CAE+ belongs to the MAX4580/MAX4590/MAX4600 family of dual analog switches. While sharing identical electrical characteristics and pinouts, the MAX4590 specifically provides two normally open switches. This distinguishes it from the MAX4580, which offers two normally closed switches, and the MAX45600, which combines one normally open and one normally closed switch within the same package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4580CAE+ and MAX4600CAE+ are pin-compatible alternatives within the same series. The MAX4580CAE+ provides two normally closed switches, while the MAX4600CAE+ offers one normally open and one normally closed switch. Verify that the specific switch state (normally open vs. normally closed) aligns with the circuit design requirements before substitution.
