ADCMP350YKSZ-REEL7

Overview

The ADCMP350YKSZ-REEL7 is a comparator and reference circuit featuring an internal 0.6 V reference connected to the inverting input. It operates within a supply voltage range of 2.25 V to 5.5 V, consuming 10 µA of supply current. The device provides high voltage tolerance up to 22 V on both the VIN and open-drain output pins. Key electrical characteristics include a typical propagation delay of 5 µs, 10 nA input bias current at low voltages, and 15 mV hysteresis. It functions reliably across a temperature range of −40°C to +125°C.

Feature Summary

• Integrates a fixed 0.6 V internal reference voltage for simplified threshold detection without external components.
• Features high-voltage tolerant inputs and outputs capable of withstanding up to 22 V, suitable for monitoring higher voltage rails.
• Designed for ultra-low power consumption with a supply current of 10 µA, extending battery life in portable applications.
• Utilizes a compact 4-lead SC-70 package to minimize board space requirements.

Applications

• Voltage detectors
• Microprocessor systems
• Battery monitors

Procurement Notes

Verify the specific suffix YKSZ corresponds to the RoHS-compliant REEL7 packaging configuration. Confirm that the inverting input connection matches the system design requirements, as this variant differs from non-inverting models in the same family. Ensure the 22 V tolerance aligns with the maximum expected input signal levels to prevent damage.

Selection Notes

Select this component when an inverting logic response is required relative to the internal 0.6 V reference. Consider alternative models like the ADCMP354 or ADCMP356 if a non-inverting output configuration or push-pull drive capability is necessary instead of the open-drain structure provided here.

Part Context

This part belongs to the ADCMP35x series of comparators and reference circuits manufactured by Analog Devices. The series includes variants with different input polarities and output stages, all sharing the same core architecture, low power specifications, and high voltage tolerance capabilities within the SC-70 footprint.

Replacement Considerations

Direct substitutes within the same family include ADCMP354YKSZ-REEL7 (non-inverting, open-drain) and ADCMP356YKSZ-REEL7 (non-inverting, push-pull). Verify pin compatibility and logic polarity before substitution.
