MAX4668ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4668ESE is a dual SPST CMOS analog switch in a 16-pin Narrow SOIC package. It features a maximum on-resistance of 2.5Ω with guaranteed matching of 0.5Ω and flatness of 0.5Ω over the signal range. Operating from +4.5V to +36V single or ±4.5V to ±20V dual supplies, it handles Rail-to-Rail signals. Key electrical parameters include 5nA maximum off-leakage current at +85°C, 450pC charge injection, 65pF off-capacitance, -66dB crosstalk at 1MHz, and turn-on/turn-off times up to 400ns/300ns under dual supply conditions.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Rail-to-Rail analog signal handling capability across the full supply voltage range.
• Low on-resistance with guaranteed channel matching and flatness for low-distortion performance.
• TTL/CMOS-compatible control inputs ensuring logic compatibility with standard digital systems.

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in electronic switching circuits
• Audio-signal routing in communication systems
• Test equipment signal path selection

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' confirms the industrial temperature range (-40°C to +85°C) and 'SE' denotes the 16-pin Narrow SOIC package. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure power-supply sequencing is managed to prevent latch-up during startup.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-voltage single or dual supply operation is required alongside low distortion. The MAX4668 provides two normally open switches; verify that the 2.5Ω on-resistance meets the application's voltage drop requirements. Consider the MAX4667 or MAX4669 if normally closed or mixed configurations are necessary instead.

Analog Switches, Multiplexers, Demultiplexers Part Context

Part of the MAX4667/MAX4668/MAX4669 family of dual SPST CMOS analog switches manufactured by Analog Devices (Maxim Integrated). These devices serve as solid-state alternatives to mechanical relays, offering reduced board space and increased reliability in automatic test equipment and signal routing applications.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4668 and MAX4669?

The MAX4668 contains two normally open (NO) switches, whereas the MAX4669 contains one normally closed (NC) and one normally open (NO) switch.

How does the device handle overvoltage conditions?

Internal protection diodes clamp signals exceeding the supply rails. For proper operation without reducing the signal range, external blocking diodes should be added if power-supply sequencing cannot be guaranteed.

What is the maximum continuous current rating?

The continuous current rating for the COM_, NO_, and NC_ pins is ±100mA.
