MAX4528CPA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4528CPA+ is a low-voltage, CMOS analog phase-reversal switch designed for high-speed applications. It operates from a +2.7V to +12V single supply or ±2.7V to ±6V dual supplies. The device features an on-resistance of 110Ω max with 7Ω match between switches at ±5V. Leakage current is 0.5nA at +25°C and 20nA at +85°C. Logic inputs have 0.8V to 2.4V thresholds for TTL/CMOS compatibility. It handles rail-to-rail analog signals and offers 2kV ESD protection.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'PA' corresponds to the 8-pin Plastic DIP package as documented in the official Maxim Integrated ordering information. Confirm that the component meets the required operating temperature range of 0°C to +70°C for the 'C' grade before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a phase-reversal function is required within a compact 8-pin footprint. Ensure the application voltage stays within the +2.7V to +12V single or ±2.7V to ±6V dual supply limits. Consider the 110Ω on-resistance and charge injection characteristics for precision signal paths.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4528 is part of the Maxim Integrated low-voltage analog switch family. It is specifically engineered for DC and low-frequency signal phase-reversal applications. The device integrates two normally open and two normally closed switches in a bridge configuration to optimize both DC and AC symmetry.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consult the datasheet for alternative parts such as the MAX4526 or MAX4527 if higher voltage operation is required. Verify pinout and electrical parameter compatibility before substituting any other analog switch ICs.

Analog Switches, Multiplexers, Demultiplexers FAQ

Can the MAX4528 reverse the phase of a single grounded signal?

No, the MAX4528 cannot reverse the phase or polarity of a single grounded signal; it is designed for out-of-phase balanced signals.

What is the maximum ESD protection rating?

The device provides transition time 2kV ESD protection per Method 3015.7.

How does the logic input threshold behave with different supplies?

Increasing V- has no effect on logic-level thresholds, but the thresholds remain CMOS/TTL compatible when V+ is between 4.5V and 12V.
