MAX4528CUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4528CUA+ is a low-voltage CMOS analog switch configured as a phase-reversal switch, optimized for high-speed applications. It operates from a +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 at ±5V and 175Ω at +5V. On-resistance matching between switches is limited to 7Ω (max) at ±5V. 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. It is housed in an 8-pin µMAX package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CUA+' against the manufacturer's official documentation to confirm the commercial temperature range and lead-free status. Ensure the ordering code matches the exact package style required for your PCB layout. Cross-reference the component marking with the datasheet pinout diagram to prevent installation errors during assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when bipolar or unipolar low-voltage operation is required for phase-reversal tasks. Verify that the system supply voltage falls within the specified operational limits for both single and dual supply configurations. Consider the thermal derating requirements if operating near the upper temperature limit in the compact µMAX package.
