MAX4527CUA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4527CUA is a phase-reversal analog switch optimized for low-power applications. It operates from single supplies of +4.5V to +36V or dual supplies of ±4.5V to ±18V. The device features an on-resistance of 175Ω maximum, matched between switches to 8Ω maximum. Leakage current is limited to 0.5nA at +25°C and 10nA at +85°C. Digital inputs have 0.8V to 2.4V logic thresholds for TTL/CMOS compatibility. Charge injection is 10pC maximum with a match of 2pC maximum. Transition time is 250ns maximum. The component is housed in an 8-pin µMAX package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CUA' corresponds to the 8-pin µMAX package and the C-grade temperature range (0°C to +70°C). Confirm that the ordering code matches the manufacturer's current naming conventions, as legacy part numbers may require cross-referencing with official distributor databases to ensure correct physical dimensions and electrical specifications are met.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4527 over the MAX4526 when lower power consumption is prioritized over high-speed performance. The MAX4527 offers identical analog characteristics but utilizes a slower logic-level translator to reduce current draw. Ensure the application requires phase-reversal functionality rather than simple SPDT switching, as this device is specifically designed for balanced signal processing.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4526/MAX4527 family of phase-reversal analog switches manufactured by Maxim Integrated, now part of Analog Devices Inc. The series provides integrated bridge configurations for DC and low-frequency signal processing. The MAX4527 variant is distinct within the family due to its optimization for low-power operation while maintaining rail-to-rail signal handling capabilities.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4526CUA serves as the high-speed counterpart within the same package and pinout. Verify if the transition time requirements exceed the MAX4527's 250ns limit before substituting.
