ADCMP396ARZ

Overview

The ADCMP396ARZ is a quad rail-to-rail input, low power analog comparator manufactured by Analog Devices Inc. It operates from a single supply voltage ranging from 2.3 V to 5.5 V and draws a quiescent current of 41.6 μA typical at 25°C. The device features a common-mode input voltage range extending 200 mV beyond the supply rails and includes an undervoltage lockout (UVLO) monitor that guarantees a logic low output when VCC is below 0.9 V. It incorporates a buffered reference output voltage of 1 V ± 0.9% and offers a typical input offset voltage of 1 mV across the full common-mode range. The component is housed in a 16-lead narrow body SOIC package.

Feature Summary

• Quad rail-to-rail input architecture allowing operation 200 mV beyond supply rails
• Integrated 1 V buffered reference output for precise threshold setting
• Undervoltage lockout ensures defined logic low state during power-up
• Low power consumption suitable for battery-powered systems

Applications

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

Procurement Notes

Verify the specific ordering suffix ARZ corresponds to the 16-lead narrow body SOIC package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected component matches the exact quad comparator configuration required for the design specifications.

Selection Notes

Select this component for applications requiring multiple independent comparison channels within a single integrated circuit. The rail-to-rail input capability supports low-voltage signal processing without level shifting. The internal reference simplifies circuit design by eliminating external precision resistors for threshold generation.

Part Context

This part belongs to the ADCMP39x family of comparators, which includes single-channel (ADCMP394) and dual-channel (ADCMP395) variants. All members share similar electrical characteristics, including low power consumption and rail-to-rail inputs, but differ in channel count and physical package dimensions to accommodate varying pin counts.

Replacement Considerations

Direct functional substitutes within the same family include the ADCMP394ARZ and ADCMP395ARZ, though these offer different channel counts and package types.
