ADCMP392ARZ

Overview

The ADCMP392ARZ is a dual-channel analog comparator from Analog Devices, housed in an 8-lead narrow body SOIC package. It operates on a single supply voltage ranging from 2.3 V to 5.5 V and draws a quiescent current of 22.1 µA typical. The device features rail-to-rail common-mode input voltage capability extending 200 mV beyond the rails, with a typical input offset voltage of 1 mV. It includes an undervoltage lockout (UVLO) mechanism that guarantees a logic low output state when the supply voltage is below 0.9 V.

Feature Summary

• Features rail-to-rail input capability allowing operation 200 mV beyond supply rails
• Includes undervoltage lockout ensuring defined logic low output during power-up
• Utilizes open-drain output stage requiring external pull-up resistor
• Designed for 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 8-lead narrow body SOIC package variant. Confirm that the component meets RoHS compliance standards as indicated in official documentation. Ensure compatibility with the required operating temperature range of −40°C to +125°C for your specific application environment before finalizing procurement.

Selection Notes

Select this component for applications requiring dual independent comparison channels within a compact surface-mount footprint. Consider the open-drain output architecture when designing interface circuits, as an external pull-up resistor is mandatory for proper high-state logic levels. Evaluate the propagation delay characteristics against system timing requirements, noting that performance varies with supply voltage and load conditions.

Part Context

This part belongs to the ADCMP39x family of single/dual/quad comparators designed for general-purpose use. It shares architectural similarities with the ADCMP391 (single channel) and ADCMP393 (quad channel), offering consistent electrical specifications across the series. The family is optimized for low-voltage, low-power operations in portable and industrial electronics.

Replacement Considerations

Direct functional substitutes within the same package include the ADCMP391 for single-channel needs or the ADCMP393 for quad-channel requirements. Verify pinout compatibility and electrical parameter alignment, particularly regarding input offset voltage and supply current, when considering alternative manufacturers' parts.
