Overview
The LMX393AUA+T is a dual general-purpose comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 1.8V to 5.5V and supports an extended automotive temperature range of -40°C to +125°C. The device features low supply current consumption, with typical values around 60µA per comparator at 5.0V. It utilizes an open-drain output configuration and includes input common-mode voltage range that extends to ground. The component is designed for low-voltage applications requiring small package footprints.
Feature Summary
- Drop-in pin-for-pin compatible replacement for LMV331/LMV393/LMV339 series
- Low supply current consumption optimized for battery-powered electronics
- Input common-mode voltage range includes ground potential
- No phase reversal occurs for overdriven inputs
Applications
- Mobile communications devices
- Automotive applications
- Battery-powered electronics
- General-purpose portable devices
Procurement Notes
Verify the specific ordering suffix '+T' indicates tape and reel packaging when sourcing this component. Confirm the 'A' designation aligns with the required temperature grade specifications. Ensure compatibility with existing board layouts due to the µMAX package dimensions. Check for RoHS compliance status as indicated by the '+' suffix in procurement documentation.
Selection Notes
Select this component for designs requiring dual comparators in a compact µMAX package. It serves as a direct substitute for legacy LMV393 designs without layout changes. Consider the open-drain output requirement for pull-up resistor implementation. Evaluate the low supply current benefit against system power budget constraints.
Part Context
This part belongs to the LMX331/LMX393/LMX339 family of general-purpose, low-voltage comparators. Manufactured using advanced submicron CMOS technology, these devices offer superior performance compared to BiCMOS or bipolar versions. The LMX393 variant specifically provides dual channels within tiny packages suitable for space-constrained applications.
Replacement Considerations
LMX393AUA+T is a drop-in replacement for LMV393AUA. Verify pin compatibility before substitution.
