ADCMP352YKS-REEL7

Overview

The ADCMP352YKSZ-REEL7 is a comparator and reference circuit from the Analog Devices ADCMP350/ADCMP354/ADCMP356 family, housed in a 4-lead SC-70 package. It operates on a supply voltage range of 2.25 V to 5.5 V with a typical supply current of 10 µA. The device features a 0.6 V internal reference, 15 mV hysteresis, and a propagation delay of 5 µs. Input pins tolerate voltages up to 22 V, while the operating temperature range spans from -40°C to +125°C.

Feature Summary

• Integrates a fixed 0.6 V on-chip reference for simplified threshold detection without external components.
• Features high-voltage tolerant input structures capable of handling signals up to 22 V independently of the supply voltage.
• Designed for ultra-low power consumption with a 10 nA input bias current and 10 µA supply current.
• Packaged in a space-efficient 4-lead SC-70 form factor suitable for portable and battery-powered applications.

Applications

• Voltage detectors
• Microprocessor systems
• Battery monitors

Procurement Notes

Verify the specific output configuration required for the design, as the datasheet defines distinct models within this series: ADCMP350 (open-drain active low), ADCMP354 (open-drain active high), and ADCMP356 (push-pull active high). Confirm that the ordering suffix matches the desired output stage type to ensure functional compatibility with the target circuit logic requirements.

Selection Notes

Select this component when a general-purpose comparator with an integrated reference is needed for low-power environments. The wide input voltage tolerance allows direct interfacing with higher voltage sensors or signal lines without level shifting. Ensure the application does not require shutdown modes or programmable hysteresis beyond the fixed 15 mV value provided by the standard architecture.

Part Context

This part belongs to the ADCMP35x series of comparators and reference circuits manufactured by Analog Devices. The series is designed for general-purpose applications requiring high performance over a wide temperature range. The specific model variant determines the output stage configuration, while all share common electrical characteristics such as low power consumption and high input voltage tolerance.

Replacement Considerations

Direct substitutes include ADCMP350YKSZ-REEL7 and ADCMP354YKSZ-REEL7 from the same manufacturer. These parts share identical pinouts and core specifications but differ in output stage polarity and type. Verify that the alternative output configuration aligns with the system's input requirements.
