MAX385CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX385CSE+ is a precision, low-voltage analog switch featuring two double-pole single-throw (DPST) channels. It operates with a single positive supply from +3V to +15V or split supplies from ±3V to ±8V. The device maintains an on-resistance of less than 35Ω, guaranteed to match within 2Ω between channels and remain flat over the specified analog signal range. It offers fast switching with turn-on times under 175ns and turn-off times under 100ns. Power consumption is extremely low at less than 10µW, with charge injection guaranteed below 5pC. The component utilizes CMOS logic inputs for compatibility with standard logic levels.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE+' against official documentation to confirm the package type, temperature range, and lead-free status. Ensure that any ordering suffixes are interpreted strictly according to the manufacturer's part numbering system, as they define physical and environmental specifications rather than functional changes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual DPST switching is required in low-voltage environments. It is suitable for applications demanding high accuracy due to matched on-resistance and low charge injection. Verify that the operating voltage range aligns with the available single or dual power rails in the target design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX381/MAX383/MAX385 family of precision analog switches. While sharing similar fabrication processes and core electrical characteristics, the MAX385 specifically provides two DPST channels, distinguishing it from the SPST MAX381 and the SPDT MAX383. All variants share pin-compatible footprints for easy design flexibility.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet indicates pin-compatibility with DG401/DG403/DG405 devices. Engineers should verify if these alternative part numbers meet the specific electrical requirements of the application before substitution.
