Overview
The LMX393AKA+T is a dual general-purpose low-voltage comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.8V to 5.5V and supports an automotive temperature range from -40°C to +125°C. The device features an open-drain output, includes internal 2mV hysteresis for noise immunity, and draws approximately 60µA per comparator at 5V. It utilizes advanced submicron CMOS technology.
Feature Summary
- Internal 2mV hysteresis prevents output oscillations caused by noise or slow-moving input signals
- Low supply current consumption with performance optimized for battery-powered applications
- Input common-mode voltage range extends to ground without phase reversal
- Designed for automotive environments with extended operating temperature capabilities
Applications
- Mobile communications devices
- Automotive electronic systems
- Battery-powered electronics
- General-purpose portable devices
Procurement Notes
Verify component authenticity through authorized distributors as the part may be subject to obsolescence. Confirm RoHS compliance status via official documentation. Ensure storage conditions adhere to moisture sensitivity level requirements. Validate package markings against ordering information to prevent counterfeit substitution during assembly.
Selection Notes
Select this component when low-voltage operation and compact SOT-23-8 packaging are required. The integrated hysteresis eliminates the need for external feedback resistors in noisy environments. Consider alternative packages if higher channel counts or different form factors are necessary for the specific design constraints.
Part Context
This device belongs to the LMX331/LMX393/LMX339 family of comparators. It serves as a drop-in replacement for LMV331/LMV393/LMV339 series components. The LMX393 variant specifically provides two independent comparators in an 8-pin configuration, offering superior performance over traditional BiCMOS or bipolar versions.
