Overview
The MAX9101EUK+T is a micropower analog comparator from Analog Devices, optimized for single-supply operation between 1.0V and 5.5V. It features an open-drain output stage suitable for mixed-voltage designs. The device consumes 5µA quiescent current with a propagation delay under 4µs. Input common-mode range extends to the negative rail, while the output supports pull-up voltages up to 6.0V independent of supply voltage.
Feature Summary
- Ultra-low voltage operation down to 1.0V
- Open-drain output stage for mixed-voltage compatibility
- Wide input common-mode range including the negative rail
- Minimal supply current increase during switching
Applications
- Single-cell battery-powered systems
- Logic-level translation in portable electronics
- Closed-loop sensor applications
- Battery-powered instrumentation
Procurement Notes
Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and lead-free packaging specifications against the latest datasheet revision. Ensure ordering suffixes match required package types and tape-and-reel configurations. Validate temperature ratings for intended operating environments.
Selection Notes
Select this component when ultra-low voltage operation below 2V is required alongside minimal power consumption. The open-drain output facilitates interfacing with higher voltage logic levels without level shifters. Consider the MAX9100 variant if push-pull output drive capability is preferred over open-drain flexibility.
Part Context
This part belongs to the MAX9100/MAX9101 family of micropower comparators designed for battery-operated devices. It shares core electrical characteristics with the MAX9100 but differs in output topology. The SOT23-5 package provides a compact footprint for space-constrained portable applications.
Replacement Considerations
MAX9100EUK+T serves as a functional substitute requiring only output stage adaptation due to its push-pull configuration instead of open-drain.
