MAX4690CAE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4690CAE is a dual SPST CMOS analog switch featuring a maximum on-resistance of 1.25Ω with guaranteed matching and flatness of 0.3Ω over the signal range. It supports single-supply operation from +4.5V to +36V or dual supplies from ±4.5V to ±20V, utilizing a separate logic supply pin for TTL/CMOS compatibility. The device handles rail-to-rail analog signals with off-leakage current limited to 5nA max at +85°C. Packaged in a 16-SSOP format, it operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CAE indicates the commercial temperature grade (0°C to +70°C) and SSOP package configuration. Confirm that the ordering code matches the exact manufacturer part number to ensure correct electrical characteristics and physical dimensions. Cross-reference the datasheet revision date to validate parameter consistency.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and high precision are required due to its matched on-resistance. Ensure the application voltage does not exceed the specified single or dual supply limits. Consider the thermal dissipation capabilities if operating near the upper temperature limit. Verify that the logic input levels align with the system's control voltage requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4680/MAX4690/MAX4700 family of dual analog switches. While sharing similar electrical specifications, the MAX4690 specifically provides two normally open switches, distinguishing it from the MAX4680 (normally closed) and MAX4700 (mixed). This configuration is suitable for applications requiring standard switching without break-before-make timing guarantees.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4690EAE offers the same functionality with an extended industrial temperature range (-40°C to +85°C). MAX4690CWE provides an alternative 16-Wide SOIC package option. Ensure any substitute maintains the 1.25Ω on-resistance and compatible pinout.
