MAX4597EXK+

Overview

The MAX4597EXK+ is a low-voltage, single-supply SPST CMOS analog switch manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 2.7V to 5.5V and features a typical on-resistance of 10 ohms. The device supports rail-to-rail signal handling and includes an enable pin for power management. Packaged in the ultra-small SC-70-5 footprint, it is designed for portable applications requiring minimal board space.

Feature Summary

• Ultra-small SC-70-5 surface-mount package
• Single-supply operation from 2.7V to 5.5V
• Rail-to-rail analog signal switching capability

Applications

• Portable consumer electronics
• Battery-powered measurement equipment
• Signal routing in communication systems

Procurement Notes

Verify the specific suffix 'EXK+' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and temperature grade. Ensure compatibility with standard SC-70-5 footprints during PCB layout. Cross-reference the component marking code with current production batches to avoid counterfeit risks.

Selection Notes

Select this component when space constraints are critical due to its SC-70-5 package. It is suitable for designs requiring single-supply operation up to 5.5V. Verify that the required on-resistance and leakage current specifications align with the application's signal integrity requirements before finalizing the design.

Part Context

This part belongs to the Maxim MAX459x family of low-voltage analog switches. The series is characterized by high performance in small packages, targeting mobile and handheld devices. The MAX4597 specifically provides a single channel, distinguishing it from dual or quad variants within the same product line.

Replacement Considerations

Check for direct substitutes such as the MAX4597CPE+ or MAX4597ESE+ based on required package type (TSSOP/SOIC vs. SC-70). Verify pinout compatibility and electrical parameter equivalence before substitution.
