MAX4544ESA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4544ESA+ is a precision, dual analog switch designed for single +2.7V to +12V supply operation. It features a single-pole/double-throw (SPDT) configuration with low power consumption of 5µW and low leakage currents of 100pA maximum. The device offers fast switching speeds with turn-on time up to 100ns and turn-off time up to 75ns at +5V. Key electrical parameters include a maximum on-resistance of 60Ω, 2Ω maximum matching between channels, and 6Ω maximum on-resistance flatness. Charge injection is guaranteed at 5pC maximum. The component provides over 2000V ESD protection per Method 3015.7 and operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. The 'ESA' designation indicates an 8-pin SOIC package rated for industrial temperatures (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with single-supply voltage requirements ranging from +2.7V to +12V.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4544ESA+ when a single-pole/double-throw configuration is required for signal routing. This part is appropriate for applications demanding low power consumption and fast switching speeds under single-supply conditions. Verify that the 60Ω maximum on-resistance meets system impedance requirements. Consider the 8-pin SOIC package dimensions for PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4544ESA+ belongs to the MAX4541–MAX4544 family of low-voltage, single-supply analog switches. While the MAX4541, MAX4542, and MAX4543 are dual single-pole/single-throw (SPST) devices, the MAX4544 specifically provides a single-pole/double-throw (SPDT) configuration. All members of this series share similar electrical characteristics regarding power consumption and switching speed.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4544ESA+ is pin-compatible with the MAX323, MAX324, and MAX325. Designers may consider these alternatives if existing board layouts require direct substitution without schematic changes.
