ADCMP361YRJZ-REEL7

Overview

The ADCMP361YRJZ-REEL7 is a single low-power comparator with an integrated 400 mV reference, housed in a 5-lead SOT-23 package. It operates on a supply voltage ranging from 1.7 V to 5.5 V and draws a typical quiescent current of 6.5 µA. The device features dual open-drain outputs capable of sinking greater than 5 mA, ensuring compatibility with various logic levels up to the maximum supply voltage. Internal hysteresis is set at approximately 9.3 mV typical, while input bias current remains below 5 nA. Threshold accuracy is specified at ±0.275% at 25°C.

Feature Summary

• Integrates a precise 400 mV internal reference for monitoring low-voltage supplies
• Provides dual open-drain outputs supporting both inverting and noninverting configurations
• Includes built-in hysteresis to prevent output oscillation caused by noise or slow signals
• Operates within a wide supply range suitable for portable and battery-powered applications

Applications

• Li-Ion battery monitoring systems
• Threshold detectors for voltage supervision
• Relay driving circuits
• Optoisolator driving interfaces
• Industrial control system inputs

Procurement Notes

Verify that the specific ordering suffix matches the required automotive qualification status, as commercial and automotive models may have differing specifications. Confirm RoHS compliance requirements align with project standards. Ensure the reel packaging format meets assembly line handling capabilities. Cross-reference the manufacturer part number against the latest datasheet revision to confirm pinout and electrical characteristics remain unchanged.

Selection Notes

Select this component when a fixed low-voltage threshold detection is required without external resistor dividers. The integrated reference simplifies design by eliminating tolerance stacking errors associated with external components. Consider the open-drain output structure if level shifting to voltages higher than the supply rail is necessary. Evaluate the propagation delay characteristics against signal speed requirements, as the device is optimized for low power rather than high-speed switching.

Part Context

This device belongs to the Analog Devices comparator family designed for ultra-low power consumption. It combines analog comparison functions with a stable voltage reference in a compact surface-mount package. The architecture allows for direct interfacing with microcontrollers and digital logic gates. Its small footprint makes it ideal for space-constrained portable electronics and handheld instruments where board area is limited.

Replacement Considerations

The ADCMP361WRJZ-RL7 is a confirmed substitute part number offering identical functionality with automotive qualification.
