ADCMP395ARMZ

Overview

The ADCMP395ARMZ is a dual-channel analog comparator from Analog Devices, housed in a 10-lead MSOP package. It operates on a single supply voltage ranging from 2.3 V to 5.5 V and draws a quiescent current of 37.2 µA typical. The device features rail-to-rail common-mode input voltage capability extending 200 mV beyond the rails. It includes an integrated 1 V ± 0.9% buffered reference output. The open-drain outputs guarantee logic low states down to 0.9 V. Operating temperature range spans from −40°C to +125°C.

Feature Summary

• Dual-channel architecture with rail-to-rail input capability
• Integrated high-accuracy 1 V buffered reference output
• Low power consumption suitable for battery-powered systems
• Defined output state upon power-up via undervoltage lockout

Applications

• Battery management and monitoring
• Power supply detection
• Window comparators
• Threshold detectors and discriminators
• Microprocessor systems

Procurement Notes

Verify the specific ordering suffix ARMZ corresponds to the 10-lead MSOP package variant when sourcing. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the supply voltage applied does not exceed the absolute maximum ratings defined in the datasheet to prevent permanent damage. Check for availability constraints as distribution status may vary by region.

Selection Notes

Select this component when a dual-channel comparator with an internal reference is required. It is appropriate for designs needing rail-to-rail inputs at low supply voltages. Consider the open-drain output requirement for external pull-up resistors. Evaluate the propagation delay specifications against system timing requirements before finalizing the design.

Part Context

This part belongs to the ADCMP39x family of low-power comparators. The family includes single (ADCMP394), dual (ADCMP395), and quad (ADCMP396) channel variants. All members share similar electrical characteristics but differ in channel count and package options. The ADCMP395 specifically provides two independent comparators in a compact surface-mount package.

Replacement Considerations

Direct substitutes within the same family include the ADCMP394ARZ for single-channel applications and the ADCMP396ARZ for quad-channel configurations. Verify pin compatibility and package dimensions when swapping between these variants.
