ADCMP370AKS-REEL

Overview

The ADCMP370AKS-REEL is a general-purpose comparator from Analog Devices Inc. housed in a 5-lead SC70 package. It operates within a supply voltage range of 2.25 V to 5.5 V and consumes 4 µA of supply current. The device features an open-drain output stage capable of tolerating up to 22 V on the output and inputs. Key electrical specifications include a maximum input offset voltage of 9 mV, an input bias current of 50 nA, and an input offset current of 150 nA. It is specified for operation over a temperature range of –40°C to +85°C.

Feature Summary

• Features an open-drain output stage with high voltage tolerance on both inputs and the output pin.
• Provides rail-to-rail common-mode input range suitable for low voltage applications.
• Delivers low power consumption with minimal input bias and offset currents.

Applications

• Voltage detectors
• Battery management systems
• Analog-to-digital converters
• Portable equipment

Procurement Notes

Verify that the specific ordering suffix matches the required packaging format, as the datasheet lists multiple reel options such as REEL and REEL7 for this component family. Confirm the RoHS compliance status indicated by the 'Z' suffix if lead-free material is strictly required for the assembly process. Ensure the operating temperature range aligns with the system environment constraints before finalizing procurement.

Selection Notes

Select the ADCMP370 variant specifically when an open-drain output is necessary to interface with external pull-up voltages exceeding the supply rail. This model is appropriate for designs requiring high voltage tolerance on the input pins while maintaining low power consumption. Consider the ADCMP371 alternative only if a push-pull output structure is preferred and high-voltage input tolerance is not required.

Part Context

This component belongs to the ADCMP370/ADCMP371 series of general-purpose comparators manufactured by Analog Devices Inc. The series is designed for battery-powered and portable equipment applications due to its low power characteristics. The ADCMP370 distinguishes itself from the ADCMP371 through its open-drain output configuration, which allows for flexible logic level interfacing via external resistors.

Replacement Considerations

The ADCMP370AKS-REEL7 is a confirmed substitute part number listed in the official ordering guide. Both variants share identical electrical specifications and the 5-Lead SC70 KS-5 package option. Verify that the reel quantity requirements match the production needs when switching between these two specific ordering codes.
