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 ±5V supplies and 900Ω max at +3V single supply. On-resistance match is 7Ω max, and charge injection is 5pC max. Leakage current is 0.5nA at +25°C. Logic thresholds are 0.8V to 2.4V, ensuring TTL/CMOS compatibility. It provides 2kV ESD protection per Method 3015.7 and operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade. The 'CPA' designation indicates the 8-pin Plastic DIP package with a commercial operating temperature range of 0°C to +70°C. Confirm availability status as distribution channels may vary for legacy components.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when phase inversion of differential signals is required in low-voltage environments. Ensure the supply voltage meets the minimum requirements for the desired on-resistance performance. Verify that the logic control levels align with the system's digital interface standards.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4528 belongs to Maxim Integrated's family of low-voltage analog switches. It is distinct from standard SPST/SPDT switches due to its bridge configuration enabling signal phase reversal. It serves as a specialized alternative to discrete transistor bridges for AC symmetry optimization.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4526 and MAX4527 are referenced in the datasheet for higher voltage operation requirements. Direct pin-compatible replacements should be verified against the official manufacturer documentation to ensure functional equivalence.
