Overview
The ADCMP370AKSZ-REEL is a general-purpose comparator from Analog Devices Inc. operating within a 2.25 V to 5.5 V supply range. It features an open-drain output capable of tolerating up to 22 V, with rail-to-rail common-mode input voltage support. Key electrical specifications include a maximum input offset voltage of 9 mV, an input bias current of 50 nA, and a typical supply current of 4 µA. The device operates across a temperature range of –40°C to +85°C and is housed in a space-efficient 5-lead SC70 package.
Feature Summary
- Features high voltage tolerance on inputs and the open-drain output, allowing compatibility with systems requiring voltages up to 22 V.
- Provides rail-to-rail common-mode input range, enabling accurate signal detection across the full power supply spectrum.
- Delivers low power consumption suitable for battery-powered applications while maintaining specified performance over a wide industrial temperature range.
Applications
- Voltage detectors
- Battery management systems
- Analog-to-digital converters
- Portable equipment
Procurement Notes
Verify that the specific ordering suffix matches the required RoHS compliance status, as indicated by the presence or absence of the 'Z' character in the part number. Confirm the reel packaging format aligns with automated assembly requirements. Ensure the component meets the specified temperature range and package dimensions for the target design.
Selection Notes
Select this component when an open-drain output with high voltage tolerance is required for interfacing with different logic levels. Consider the ADCMP371 if a push-pull output stage is preferred instead of an open-drain configuration. Evaluate the low quiescent current against system power budgets for portable electronics.
Part Context
This component belongs to the ADCMP370/ADCMP371 family of general-purpose comparators manufactured by Analog Devices Inc. The series is designed for applications requiring low power consumption and robust input handling capabilities. The ADCMP370 variant specifically provides an open-drain output structure distinct from the push-pull output found in the ADCMP371 model.
Replacement Considerations
The ADCMP370AKS-REEL serves as a non-RoHS compliant alternative to the ADCMP370AKSZ-REEL within the same package and functional specification.
FAQ
What is the maximum voltage tolerance for the inputs and output?
Both the inputs and the open-drain output can tolerate voltages up to 22 V.
Does the ADCMP370 require an external pull-up resistor?
Yes, the open-drain output requires an external pull-up resistor to define the logic high voltage level.
