ADCMP395ARMZ-RL7

Overview

The ADCMP395ARMZ-RL7 is a dual-channel, rail-to-rail input, low-power analog comparator manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.3 V to 5.5 V and draws a quiescent current of approximately 37.2 μA at 25°C. The device features a typical input offset voltage of 1 mV across the common-mode range and includes an integrated 1 V ± 0.9% buffered reference output. It utilizes open-drain outputs and functions within an extended temperature range of −40°C to +125°C.

Feature Summary

• Dual-channel architecture with rail-to-rail common-mode input capability extending 200 mV beyond supply rails
• Integrated high-accuracy 1 V buffered reference output for precise threshold setting
• Open-drain output stage ensuring defined logic low state during undervoltage lockout conditions

Applications

• Battery management and monitoring systems
• Power supply detection circuits
• Window comparators for positive or negative voltage monitoring
• Threshold detectors and discriminators in microprocessor systems

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the required reel packaging configuration before procurement. Confirm that the ARMZ designation aligns with the intended lead-free and RoHS compliance requirements for the target assembly process. Ensure the 10-lead MSOP package dimensions fit the designated PCB footprint constraints.

Selection Notes

Select this component when a dual-channel solution with integrated reference functionality is required to minimize external passive components. The low quiescent current makes it suitable for battery-powered applications where power efficiency is critical. Verify that the open-drain output requirement matches the downstream digital logic interface pull-up specifications.

Part Context

This part belongs to the ADCMP39x family, which includes single (ADCMP394) and quad (ADCMP396) variants. All members share identical electrical characteristics, including the 1 V reference and rail-to-rail inputs, differing only in channel count and package type. The ADCMP395 specifically provides two comparators in a compact 10-lead MSOP package.

Replacement Considerations

Direct functional substitutes within the same family include the ADCMP394ARZ for single-channel needs or the ADCMP396ARZ for four-channel requirements. Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
