ADCMP393ARUZ-RL7

Overview

The ADCMP393ARUZ-RL7 is a quad comparator from Analog Devices Inc. It operates on a single supply voltage ranging from 2.3 V to 5.5 V and features rail-to-rail common-mode input voltage capability extending 200 mV beyond the rails. The device guarantees a defined logic low output state during power-up when the supply voltage is below the undervoltage lockout threshold. It draws a typical quiescent current of 26.8 µA and operates across an extended temperature range from −40°C to +125°C.

Feature Summary

• Features rail-to-rail input capability with a common-mode range extending 200 mV beyond the supply rails.
• Provides a guaranteed known logic low output state upon power-up before the supply reaches the UVLO threshold.
• Includes an integrated undervoltage lockout (UVLO) monitor for reliable startup behavior.

Applications

• Battery management and monitoring systems
• Power supply detection circuits
• Window comparators for voltage supervision
• Threshold detectors and discriminators
• Microprocessor system reset and sequencing

Procurement Notes

Verify the specific package variant, as the ADCMP393 is available in both 14-lead SOIC and TSSOP configurations. Confirm that the RL7 suffix corresponds to the required reel packaging format for your assembly line. Ensure the operating environment stays within the specified -40°C to +125°C temperature range to maintain parameter accuracy.

Selection Notes

Select this component for applications requiring low power consumption and rail-to-rail input compatibility with low-voltage supplies. The open-drain outputs require external pull-up resistors, which must be sized appropriately for the desired rise time and load capacitance. Consider the propagation delay characteristics relative to your signal overdrive voltage requirements.

Part Context

This part belongs to the ADCMP393 family of quad comparators manufactured by Analog Devices Inc. It is designed for general-purpose comparison tasks where low power and wide input range are critical. The device integrates four independent comparators into a single compact package, simplifying board space requirements for multi-channel monitoring applications.

Replacement Considerations

Check datasheets for other quad comparators with similar supply ranges and input specifications. Verify pin compatibility if substituting packages, as the SOIC and TSSOP versions have different pinouts. Ensure replacement parts support the required open-drain output configuration and UVLO functionality.
