MAX9101EUK

Overview

The MAX9101EUK is a single-channel analog comparator from the MAX9101 series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1 V to 5.5 V and consumes a typical operating current of 8 uA. The device features rail-to-rail output capability and general-purpose functionality. Key electrical parameters include a propagation delay of 4.5 us, an input offset voltage (Vos) of 10 mV, and an input bias current (Ib) of 15 nA. It supports an output current of 500 uA per channel with a common-mode rejection ratio (CMRR) of 54 dB and power supply rejection ratio (PSRR) of 54 dB. The component functions reliably across an extended temperature range from -40 C to +85 C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated applications
• Rail-to-rail output stage for maximum dynamic range
• Wide single-supply voltage operation range

Applications

• Battery-powered sensing systems
• Threshold detection circuits
• Low-power signal conditioning

Procurement Notes

Verify the specific suffix variant against official documentation, as packaging and tape/reel specifications may differ between tube and reel configurations. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory markings can vary by production batch. Ensure the selected package matches the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when low quiescent current is critical compared to speed requirements. The 4.5 us propagation delay indicates suitability for slow-response applications rather than high-speed digital interfaces. Verify that the 10 mV input offset voltage meets the precision requirements of the specific application circuit design constraints.

Part Context

This part belongs to the MAX9101 family of micropower comparators designed for low-voltage operation. The EUK suffix typically denotes the SOT-23-5 surface-mount package variant. This series emphasizes energy efficiency over high-speed performance, targeting portable and remote monitoring electronics where power conservation is a primary design constraint.

Replacement Considerations

Consult official cross-reference guides for verified substitutes. Generic replacements must match the 1 V to 5.5 V supply range and SOT-23-5 package dimensions.
