Overview
The MAX9093AKA+T is a dual general-purpose comparator in an 8-pin SOT-23 package. It operates on a single supply from +1.8V to +5.5V with a typical supply current of 65µA per channel at +5.0V. The device features open-drain outputs, input common-mode voltage range including ground, and no phase reversal for overdriven inputs. Internal hysteresis provides noise immunity. Propagation delay is typically 100ns. Operating temperature range is -40°C to +125°C.
Feature Summary
- Internal 2mV hysteresis prevents output oscillations caused by noise or slow-moving signals.
- Open-drain outputs allow flexible interfacing with various logic families.
- Input common-mode voltage range extends to include ground potential.
- No phase reversal occurs even when inputs are overdriven beyond the supply rails.
Applications
- Mobile communications
- Notebooks and PDAs
- Battery-powered electronics
Procurement Notes
Verify the component matches the exact part number MAX9093AKA+T. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated. Ensure the package type is SOT-23-8. Check for RoHS compliance markings if required by your specifications. Validate that the device is intended for industrial temperature ranges.
Selection Notes
Select this component for low-voltage portable applications requiring small footprint comparators. It serves as a pin-for-pin replacement for LMX393 devices. Consider its internal hysteresis for noisy environments. Evaluate its low supply current for battery-operated designs. Verify compatibility with single-supply systems operating between 1.8V and 5.5V.
Part Context
This device belongs to the MAX9092/MAX9093/MAX9094/MAX9095 family of general-purpose, low-voltage, tiny pack comparators. The MAX9093 specifically offers dual channels with internal hysteresis. It is designed for cost-sensitive, space-constrained applications where low power consumption is critical.
Replacement Considerations
The datasheet states it is a pin-for-pin compatible replacement for the LMX393.
FAQ
Does the MAX9093AKA+T have built-in hysteresis?
Yes, the MAX9093 includes internal 2mV hysteresis to provide noise immunity and prevent output oscillations.
What is the input common-mode voltage range?
The input common-mode voltage range includes ground (0V) and extends up to within 0.8V of the positive supply rail.
