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 automotive temperature range of -40°C to +125°C. The device features an open-drain output type with a maximum input offset voltage of 7mV at 5V and a typical supply current of 60µA per comparator at 5V. Propagation delay is typically 100ns with 100mV overdrive. It utilizes advanced submicron CMOS technology for low power consumption.
Feature Summary
- Drop-in, pin-for-pin-compatible replacement for LMV393 devices
- Advanced submicron CMOS technology for superior performance
- Wide operating temperature range suitable for automotive applications
- Low supply current and small package footprint
Applications
- Mobile Communications
- Automotive Applications
- Battery-Powered Electronics
- General-Purpose Low-Voltage Applications
Procurement Notes
Verify the component status as discontinued or obsolete through official manufacturer channels before finalizing procurement plans. Confirm RoHS compliance and lead-free packaging specifications via the latest datasheet revision. Ensure compatibility with existing PCB land patterns for the 8-pin µMAX package. Validate that the specific ordering suffix matches the required tape and reel configuration for automated assembly processes.
Selection Notes
Select this component when a low-voltage, dual-channel comparator is required in a compact µMAX package. It serves as a direct drop-in replacement for LMV393 equivalents. Consider its wide supply voltage range and automotive temperature rating for robust designs. Evaluate propagation delay and input offset voltage requirements against application needs to ensure signal integrity.
Part Context
This part belongs to the LMX331/LMX393/LMX339 series of general-purpose, low-voltage comparators. The series includes single, dual, and quad variants in tiny packages like SC70, SOT23, and µMAX. These devices are designed to offer advantages over BiCMOS or bipolar versions, including wider supply voltage ranges, better CMRR/PSRR, and improved RF immunity.
Replacement Considerations
Public confirmed substitute part numbers include MAX9092AUA.
