Overview
The ADCMP392ARZ-RL7 is a dual 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. It guarantees a defined logic low output state when the supply voltage is below the undervoltage lockout threshold.
Feature Summary
- Features rail-to-rail input capability allowing operation with signals extending beyond supply rails.
- Provides a guaranteed known power-up state by asserting a logic low output during undervoltage conditions.
- Designed for low-power applications with minimal supply current consumption suitable for battery systems.
Applications
- Battery management and monitoring
- Power supply detection
- Window comparators
- Threshold detectors and discriminators
- Microprocessor systems
Procurement Notes
Verify the specific ordering suffix RL7 corresponds to the required reel packaging configuration before procurement. Confirm that the 8-lead SOIC package meets the physical footprint requirements of the target PCB design. Ensure the operating temperature range of -40°C to +125°C aligns with the environmental specifications of the final application.
Selection Notes
Select this component when dual independent comparison channels are required within a compact surface-mount footprint. Consider the open-drain output architecture which necessitates external pull-up resistors for proper logic level interfacing. Evaluate the propagation delay characteristics against the signal speed requirements of the circuit to ensure adequate response time.
Part Context
This part belongs to the ADCMP39x family of single-supply comparators manufactured by Analog Devices. It shares architectural similarities with the single-channel ADCMP391 and the quad-channel ADCMP393. The family is characterized by its low power consumption and extended common-mode input range, making it suitable for general-purpose analog-to-digital conversion tasks.

FAQ
What is the behavior of the output during power-up?
When the supply voltage reaches 0.9 V, the device guarantees an output low logic state until the voltage exceeds the undervoltage lockout threshold.
How does the input voltage range compare to the supply rails?
The common-mode input voltage range extends 200 mV beyond both the ground and the positive supply rail (VCC).
