MAX4661CAE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4661CAE+ is a quad single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed switches with a maximum on-resistance of 2.5Ω and an on-resistance match between channels of 0.5Ω max. The device supports rail-to-rail analog signal handling and operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies. It includes TTL/CMOS-compatible control inputs via a separate logic supply pin. 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 Procurement Notes

Verify the specific ordering suffix 'CAE+' against the manufacturer's current datasheet to confirm the 16-pin SSOP package and 0°C to +70°C operating temperature range. Ensure that the logic supply requirements and power sequencing align with the system design, as improper sequencing may affect reliability. Cross-reference the part number with official distributor catalogs to confirm current availability status.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high channel matching are critical for signal integrity in analog switching applications. The MAX4661 variant is appropriate for designs requiring normally closed contacts. Consider the wide supply voltage range and separate logic supply pin for flexibility in interfacing with various digital control circuits. Evaluate thermal dissipation requirements based on the SSOP package power derating characteristics.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4661CAE+ belongs to the MAX4661/MAX4662/MAX4663 family of quad SPST CMOS analog switches. This series is designed to replace mechanical relays in automatic test equipment and data acquisition systems due to lower power consumption and higher reliability. The 'C' designation indicates the commercial temperature grade, while 'AE' specifies the SSOP package type.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include the MAX4662CAE+ (normally open configuration) and MAX4663CAE+ (mixed NC/NO with break-before-make). For broader replacements, verify pinout compatibility and electrical specifications such as on-resistance and supply voltage ranges against other quad SPST analog switches.
