MAX4544CPA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4544CPA+ is a single-pole/double-throw (SPDT) analog switch from the MAX4541–MAX4544 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from +2.7V to +12V and consumes less than 5µW of power. The device features a maximum on-resistance (RON) of 60Ω with a typical value of 33Ω at +5V. Key electrical parameters include a maximum charge injection of 5pC, off-leakage current of 100pA, and switching times of 100ns (ton) and 75ns (toff). It provides over 2000V ESD protection per Method 3015.7 and is housed in an 8-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official datasheets to confirm pinout compatibility and electrical specifications before integration. Ensure that the operating temperature range aligns with the specific environmental requirements of the target application. Cross-reference ordering information to validate the exact package type and suffix designations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4544CPA+ when a single SPDT switch is required within a low-voltage, single-supply environment. Consider its 60Ω maximum on-resistance and fast switching speeds for signal routing applications. Evaluate the 8-pin PDIP package constraints against available board space and thermal dissipation needs compared to surface-mount alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4544CPA+ belongs to the MAX4541–MAX4544 series of precision dual analog switches. While the MAX4541, MAX4542, and MAX4543 are dual SPST devices, the MAX4544 specifically functions as a single SPDT switch. This series is designed for low-power, low-voltage applications requiring high reliability and minimal signal distortion.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4544CSA+ offers the same functionality in an SOIC-8 surface-mount package. For extended temperature ranges, the MAX4544EPA+ is available in an 8-pin Plastic DIP. Verify pin compatibility and electrical characteristics before substituting.
