Overview
The ADCMP371AKS-REEL7 is a general-purpose analog comparator manufactured by Analog Devices Inc. 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 a push-pull output stage, rail-to-rail common-mode input range, and high voltage tolerance on inputs up to 22 V. 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. Propagation delay is specified at 5 µs with a 10 mV input overdrive. It is rated for operation from –40°C to +85°C and is housed in a space-efficient 5-lead SC70 package.
Feature Summary
- Push-pull output stage providing internal pull-up without external resistors
- High voltage tolerance on inputs and open-drain outputs up to 22 V
- Rail-to-rail common-mode input range capability
- Low power consumption suitable for battery-powered applications
Applications
- Voltage detectors
- Battery management systems
- Analog-to-digital converters
- Portable equipment
Procurement Notes
Verify the specific ordering suffix REEL7 against the manufacturer's official documentation to confirm packaging details and reel specifications. Ensure the component matches the required temperature range and package type for your design. Cross-reference the datasheet revision history for any updates to electrical characteristics or application notes before finalizing procurement.
Selection Notes
Select this component when a low-power, general-purpose comparator with a push-pull output is required. It is suitable for designs needing rail-to-rail input compatibility and high voltage tolerance on signal lines. Consider the 5-lead SC70 package for space-constrained layouts. Verify that the propagation delay and offset voltage meet the precision requirements of the target application.
Part Context
The ADCMP371AKS-REEL7 belongs to the ADCMP370/ADCMP371 family of general-purpose comparators from Analog Devices. This series is designed for low-voltage, battery-operated applications. The ADCMP371 variant specifically utilizes a push-pull output structure, distinguishing it from the open-drain ADCMP370. Both share similar input characteristics and operating voltage ranges.
Replacement Considerations
The ADCMP370AKS-REEL7 is a related part within the same family but features an open-drain output instead of push-pull. Direct substitution requires evaluating if the circuit can accommodate the need for an external pull-up resistor associated with the open-drain configuration.
