MAX4528CUA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4528CUA+ is a low-voltage CMOS analog switch configured as a phase-reversal switch. It operates from +2.7V to +12V single supply or ±2.7V to ±6V dual supplies. The device features two SPDT switches with a maximum on-resistance of 110Ω and a match between switches of 7Ω max. It handles rail-to-rail analog signals with leakage current of 0.5nA at +25°C. Digital inputs have 0.8V to 2.4V logic thresholds for TTL/CMOS compatibility. Charge injection is 5pC max, and it offers 2kV ESD protection per Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CUA' corresponds to the commercial temperature range (0°C to +70°C) and the 8-pin µMAX package. Confirm RoHS compliance status through official manufacturer documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when phase inversion of balanced signals is required in low-voltage environments. Ensure the application operates within the specified single or dual supply voltage limits. Verify that the 110Ω on-resistance meets the system's signal integrity requirements. Consider thermal dissipation limits if operating near the upper temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4528 belongs to Maxim Integrated's family of low-voltage analog switches. It is distinct from the MAX4526/MAX4527 which support higher voltages. The CU variant specifically denotes the commercial temperature grade housed in an 8-lead µMAX package, differentiating it from industrial grades or other package types like SOIC or DIP.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements may include other MAX4528 variants with different temperature ranges or packages, such as MAX4528EUA for extended temperature. Cross-reference with MAX4526/MAX4527 only if higher voltage operation is needed, noting differences in supply ranges.
