Overview
The ADCMP370AKSZ-REEL7 is a general-purpose comparator from Analog Devices Inc. operating within a 2.25 V to 5.5 V supply voltage range with a typical supply current of 4 µA. It features an open-drain output stage capable of tolerating up to 22 V. Key electrical specifications include a maximum input offset voltage of 9 mV, an input bias current of 50 nA, and rail-to-rail common-mode input capability. The device operates over 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 logic levels up to 22 V.
- Provides rail-to-rail common-mode input range for flexible signal interfacing across the full supply voltage span.
- Designed for low power consumption, making it suitable for battery-powered and portable electronic applications.
Applications
- Voltage detectors
- Battery management systems
- Analog-to-digital converters
- Low voltage applications
- Portable equipment
Procurement Notes
Verify that the specific ordering suffix matches the required packaging format, as the datasheet lists multiple variants including REEL and REEL7 options. Confirm the RoHS compliance status indicated by the 'Z' suffix if lead-free components are strictly required for the assembly process. Ensure the selected part number aligns with the specified temperature range and package dimensions for the target PCB layout.
Selection Notes
Select this component when an open-drain output with high voltage tolerance is necessary for interfacing with different logic families. Consider the 9 mV maximum input offset voltage and 50 nA input bias current for precision requirements. Evaluate the propagation delay characteristics against the system timing constraints, noting that delays vary with input overdrive and temperature conditions.
Part Context
This component belongs to the ADCMP370/ADCMP371 family of general-purpose comparators manufactured by Analog Devices Inc. The ADCMP370 variant specifically utilizes an open-drain output structure, distinguishing it from the push-pull output found in the ADCMP371 model. Both share identical input characteristics and low power profiles but differ in output drive capabilities and external circuit requirements.
Replacement Considerations
The ADCMP370AKS-REEL7 is a direct functional substitute for the ADCMP370AKSZ-REEL7, differing only in reel packaging configuration. Verify pinout compatibility and ensure the replacement maintains the required 5-lead SC70 footprint and thermal impedance characteristics for the application.
