MAX4662CAE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4662CAE+ is a quad, single-pole single-throw (SPST) CMOS analog switch featuring a maximum on-resistance of 2.5Ω. It operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies. The device includes four normally open switches with TTL/CMOS-compatible logic inputs and handles rail-to-rail analog signals. It offers low off-leakage current of 5nA max at +85°C and provides over 2kV ESD protection. The component is housed in a 16-pin SSOP package and functions within a commercial temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Low on-resistance of 2.5Ω maximum with guaranteed matching between channels
• Rail-to-rail signal handling capability for broad voltage ranges
• TTL/CMOS-compatible control inputs via a separate logic supply pin
• High reliability replacement for mechanical relays in switching applications

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Audio-signal routing in PBX and PABX systems
• Data acquisition systems and ADC front ends
• Sample-and-hold circuits in communication systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CAE+' to confirm the 16-lead SSOP package and the 0°C to +70°C commercial operating temperature range. Ensure the logic supply pin VL is correctly biased for the intended single or dual supply configuration to maintain TTL/CMOS compatibility across the full voltage range.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when low distortion and flat on-resistance are critical for signal integrity. The MAX4662 differs from the MAX4661 by using normally open switches rather than normally closed ones. Verify that the required continuous current does not exceed 200mA and that the board space constraints favor an SMD SSOP package over through-hole alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX466x family of quad analog switches manufactured by Analog Devices / Maxim Integrated. It shares the same electrical characteristics as the MAX4661 and MAX4663 but is distinguished by its four normally open switch configuration. The family is designed to replace electromechanical relays in applications requiring high reliability and low power consumption.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4661CAE+ serves as a functional substitute if normally closed switches are acceptable instead of normally open. MAX4663CAE+ is suitable where break-before-make timing is required, though it combines both NC and NO switches.
