MAX381ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX381ESE+T is a precision, low-voltage analog switch featuring two single-pole single-throw (SPST) normally open channels. It operates with a single positive supply ranging from +3V to +15V or split supplies of ±3V to ±8V. The device provides an on-resistance of less than 35Ω, guaranteed to match within 2Ω between channels and remain flat over the specified analog signal range. Key electrical parameters include a maximum turn-on time of 175ns, a maximum turn-off time of 100ns, and charge injection of less than 5pC. It supports rail-to-rail analog signal handling and maintains CMOS logic input compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer markings against official documentation. Confirm that the package type matches the narrow SOIC-16 specification. Ensure the temperature grade corresponds to the industrial range requirements for the intended application environment before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when precise analog switching with low distortion is required in low-voltage environments. Consider the 35Ω maximum on-resistance and 175ns switching speed for timing constraints. Verify that the analog signal levels fall within the supported rail-to-rail range for the chosen supply voltage configuration.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX381/MAX383/MAX385 family of precision analog switches manufactured by Analog Devices/Maxim Integrated. The MAX381 specifically offers two SPST channels, whereas the MAX383 includes SPDT configurations and the MAX385 features dual SPST switches. All variants share similar low-voltage performance characteristics and pinout compatibility.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations
