MAX4527EUA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4527EUA is a phase-reversal analog switch in an 8-pin µMAX package, optimized for low-power applications. It operates from +4.5V to +36V single supply or ±4.5V to ±18V dual supplies. The device features a maximum on-resistance of 175Ω with matching to 8Ω max. Leakage current is 0.5nA at +25°C and 10nA at +85°C. Transition time is 250ns max. Charge injection is 10pC max with 2pC matching. Logic inputs are TTL/CMOS compatible (0.8V to 2.4V thresholds). Operating temperature range is -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Applications

• Chopper-stabilized amplifiers
• Balanced modulators and demodulators
• Data acquisition systems
• Audio-signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific E suffix indicates the extended temperature range of -40°C to +85°C. Confirm the UA suffix corresponds to the 8-pin µMAX package format. Check for RoHS compliance status as indicated by the plus sign in the part number. Ensure the source document matches the official Analog Devices datasheet for accurate electrical specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4527 over the MAX4526 when lower power consumption is prioritized over switching speed. The MAX4527 offers identical analog characteristics but utilizes slower drivers for reduced current draw. Verify that the 250ns transition time meets the system timing requirements. Ensure the 175Ω on-resistance is acceptable for the application's signal integrity needs.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4527 is part of the MAX4526/MAX4527 family of phase-reversal analog switches. While sharing the same analog bridge configuration and pinout, it differs from the MAX4526 by optimizing internal drivers for lower power consumption rather than higher speed. Both devices provide rail-to-rail signal handling and TTL/CMOS compatible logic inputs within the same 8-pin footprint options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4526 serves as a functional substitute if higher switching speed is required instead of low power. Other variants like MAX4527ESA or MAX4527CPA offer different packages or temperature ranges while maintaining the same core functionality.
