ADCMP354YKS-REEL7

Overview

The ADCMP354YKSZ-REEL7 is a single-channel analog comparator with an integrated 0.6 V noninverting reference, manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.25 V to 5.5 V and features an open-drain output stage capable of tolerating up to 22 V on the input and output pins. The device consumes 10 µA to 15 µA of supply current, exhibits a propagation delay of 5 µs, and includes 15 mV of internal hysteresis. It is housed in a space-efficient 4-lead SC-70 package and is specified for operation across a temperature range of −40°C to +125°C.

Feature Summary

• Integrates a fixed 0.6 V noninverting reference voltage threshold for simplified circuit design.
• Features high-voltage tolerant input and open-drain output structures supporting up to 22 V signals.
• Provides low power consumption suitable for battery-powered applications with minimal quiescent current draw.
• Includes built-in hysteresis to prevent output oscillation caused by noise or slowly changing input signals.

Applications

• Voltage detectors
• Microprocessor systems
• Battery monitors

Procurement Notes

Verify the specific ordering suffix REEL7 against official documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status as indicated by the Z suffix in the part number. Ensure the component matches the KS-4 package outline dimensions required for your PCB layout. Cross-reference the manufacturer's latest datasheet revision to validate electrical parameters before finalizing procurement.

Selection Notes

Select this component when a noninverting comparison logic is required relative to a fixed internal reference. The open-drain output necessitates an external pull-up resistor; ensure the selected resistor value supports the desired load current and voltage levels. Consider the 5 µs propagation delay if timing constraints are critical. Verify that the 22 V tolerance aligns with the maximum expected signal amplitudes in the application environment.

Part Context

This device belongs to the ADCMP35x family of comparators and reference circuits from Analog Devices. It shares the same core architecture and performance characteristics as the ADCMP350 and ADCMP356, differing primarily in the polarity of the internal reference connection and the output stage configuration. The ADCMP354 specifically provides a noninverting response with an open-drain output.

Replacement Considerations

The ADCMP350YKSZ-REEL7 serves as a functional substitute if inverting logic is acceptable. The ADCMP356YKSZ-REEL7 may be used if a push-pull output is preferred over an open-drain configuration. Verify pin compatibility and electrical specifications before substituting.
