Overview
The MAX9100EUK-T is a micropower comparator from Analog Devices/Maxim Integrated, housed in a SOT23-5 package. It operates on a single supply of 1.0V to 5.5V with a quiescent current of 5µA. The device features a push-pull CMOS output stage capable of rail-to-rail swing and sourcing/sinking up to 5mA. Propagation delay is less than 4µs, with rise/fall times of 100ns. Input common-mode range extends from the negative rail to VCC-0.2V. Operating temperature range is -40°C to +85°C.
Feature Summary
- Ultra-low voltage operation down to 1.0V
- Push-pull CMOS output for rail-to-rail swing
- Wide input common-mode range including negative rail
- No output phase reversal for overdriven inputs
Applications
- Single-cell battery systems
- Portable electronic equipment
- Battery-powered instrumentation
- Closed sensor applications
- Logic-level translation
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the 'EUK' designation corresponds to the SOT23-5 package variant. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Check for lead-free/RoHS compliance status if mandated by project specifications. Validate pinout alignment with existing PCB footprints before final procurement.
Selection Notes
Select this component for designs requiring minimal power consumption in single-supply environments. The push-pull output is suitable for direct interfacing with digital logic without external pull-ups. Consider the 4µs propagation delay for timing-critical paths. Evaluate the 5mA drive capability against load requirements. Ensure input signals remain within the specified common-mode voltage limits for optimal performance.
Part Context
This part belongs to the MAX9100/MAX9101 family of micropower comparators. It shares architectural similarities with other Maxim low-voltage comparators but is distinct due to its specific 1.0V minimum operating voltage and push-pull output configuration. The SOT23-5 package offers a compact footprint for space-constrained portable applications.
Replacement Considerations
The MAX9101EUK+T serves as a functional alternative within the same series, differing primarily in having an open-drain output instead of push-pull. Verify that the open-drain requirement aligns with the system's pull-up resistor strategy before substituting.
