LMX393HAKA+

Overview

The LMX393HAKA+T is a dual general-purpose comparator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features an open-drain output configuration and operates within a supply voltage range of 1.8V to 5.5V for single or dual supplies. The device exhibits a maximum propagation delay of 600ns, a typical CMRR/PSRR of 70dB, and a maximum input offset voltage of 7mV at 5V. It is housed in an SOT-23-8 surface-mount package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Dual-channel architecture with open-drain outputs
• Low-voltage operation capability down to 1.8V
• Extended industrial temperature range support

Applications

• General-purpose signal comparison circuits
• Voltage monitoring applications
• Threshold detection systems

Procurement Notes

Verify the specific suffix 'T' indicating tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Check current product lifecycle status as availability may vary. Ensure the supplier provides valid traceability data for quality assurance purposes.

Selection Notes

Select this component for designs requiring low-voltage compatibility and compact SOT-23-8 packaging. Compare performance metrics such as propagation delay and offset voltage against alternative comparators if higher speed or precision is required. Consider the open-drain output limitation when designing pull-up resistor networks for the application circuit.

Part Context

This part belongs to the LMX393 series of general-purpose comparators. It serves as a pin-compatible replacement for older generations like the LM393 in certain configurations. The device is designed for cost-sensitive applications requiring reliable analog switching and comparison functions in small form factors.

Replacement Considerations

Publicly documented pin-for-pin compatible replacements include the MAX9092AUA. Verify electrical specifications match before substitution.
