MAX4541CUA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4541CUA is a dual single-pole/single-throw (SPST) analog switch from the MAX4541–MAX4544 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +2.7V to +12V supply with low power consumption of 5µW. The device features a maximum on-resistance (RON) of 60Ω at +5V, channel-to-channel matching of 2Ω, and flatness of 6Ω. Leakage current is limited to 100pA max, with charge injection capped at 5pC. Switching speeds reach tON = 150ns and tOFF = 100ns max. It includes over 2000V ESD protection per Method 3015.7 and is housed in an 8-pin µMAX package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CUA' corresponds to the 8-pin µMAX package and the 0°C to +70°C temperature range as listed in the official ordering information. Confirm that the component meets RoHS3 compliance standards if required for the assembly process. Cross-reference the manufacturer part number directly with the datasheet revision history to ensure accurate sourcing.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPST topology is required within a compact surface-mount footprint. The +2.7V minimum supply voltage makes it suitable for portable applications where power efficiency is critical. Ensure the application signal levels remain within the specified analog signal range relative to the supply voltage to maintain optimal on-resistance performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4541–MAX4544 series of low-voltage, single-supply dual analog switches. While the MAX4541 offers two SPST switches, other variants in the family include SPDT configurations like the MAX4544. The CU designation indicates commercial temperature range availability, distinguishing it from the extended temperature EA or EK variants.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible alternatives within the same family include the MAX4542 (dual NC), MAX4543 (one NO/one NC), and MAX4544 (dual SPDT). For extended temperature ranges, consider the MAX4541EUA (-40°C to +85°C). Verify package compatibility when substituting with SOIC or DIP versions.
