MAX4541CUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4541CUA+ is a precision, dual analog switch designed for single +2.7V to +12V supply operation. It features two normally open (NO) SPST channels with a maximum on-resistance of 60Ω and a typical value of 33Ω at +5V. The device offers low leakage currents of 100pA maximum and fast switching speeds, with turn-on times up to 100ns and turn-off times up to 75ns. It provides excellent channel matching with a maximum ΔRON of 2Ω and RON flatness of 6Ω. Power consumption is minimal at 5µW, making it suitable for battery-powered applications. The component operates within a commercial temperature range of 0°C to +70°C and is housed in an 8-pin µMAX package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for the 8-pin µMAX configuration. Cross-reference part numbers with authorized distributors to confirm authenticity and traceability before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPST switch with normally open contacts is required for low-voltage single-supply applications. Consider the 60Ω maximum on-resistance and 100pA leakage current specifications for signal integrity requirements. Verify that the 0°C to +70°C operating temperature range meets the environmental conditions of the target application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4541 is part of the MAX4541–MAX4544 family of low-voltage, single-supply dual analog switches. While the MAX4541 specifically contains two normally open switches, other variants in the series offer normally closed or mixed configurations. This family shares similar electrical characteristics but differs in internal switch topology and pin assignments for specific control logic.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin compatibility with the MAX323, MAX324, and MAX325 devices. These parts may serve as functional replacements if the system design accommodates their specific electrical parameters and package constraints.
