MAX4528EUA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4528EUA is a low-voltage, CMOS analog phase-reversal switch optimized for high-speed applications. 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 at ±5V and 175Ω at +5V. On-resistance matching is limited to 7Ω (±5V) and 10Ω (+5V). Leakage current is typically 0.5nA at +25°C. Charge injection is 5pC max. Logic inputs are TTL/CMOS compatible. Operating temperature range is -40°C to +85°C in an 8-pin µMAX package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Low charge injection for precision signal integrity

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 suffix 'EUA' corresponds to the industrial temperature grade (-40°C to +85°C) and the 8-pin µMAX package format. Confirm RoHS compliance status as indicated by the '+' designation if applicable. Ensure the source documentation matches the exact part number to avoid confusion with other variants like MAX4528ESA.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when bipolar or low-voltage single-supply phase reversal is required. The ±5V optimization makes it suitable for standard analog signal levels. Verify that the 110Ω on-resistance meets system loss requirements. Consider the 5pC charge injection limit for sensitive data acquisition paths where signal distortion must be minimized.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4528 series includes variants such as MAX4528CPA, MAX4528CSA, and MAX4528CUA. The MAX4528EUA specifically denotes the extended temperature range version housed in the small 8-lead µMAX surface-mount package. This family is distinct from higher-voltage counterparts like the MAX4526/MAX4527.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacement options include other MAX4528 variants with different packages or temperature ratings, such as MAX4528ESA. Cross-family replacements require verification of voltage ranges and pin compatibility.
