ADCMP371AKSZ-REEL7

Overview

The ADCMP371AKSZ-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 a typical supply current of 4 µA. 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 housed in a space-efficient 5-lead SC70 package.

Feature Summary

• Push-pull output stage providing internal pull-up capability without external resistors
• High voltage tolerance on inputs and open-drain outputs up to 22 V
• Rail-to-rail common-mode input range compatible with single-supply operation
• Low power consumption suitable for battery-powered portable equipment

Applications

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

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to tape-and-reel packaging when sourcing components. Confirm that the AKSZ variant meets RoHS compliance requirements if mandated by project specifications. Ensure the operating temperature range of –40°C to +85°C aligns with environmental conditions. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select the ADCMP371AKSZ-REEL7 when a push-pull output is required instead of the open-drain configuration found in the ADCMP370 series. This component is appropriate for applications needing rail-to-rail input compatibility and low quiescent current. Consider the 5-lead SC70 package size for space-constrained designs. Evaluate propagation delay characteristics against signal speed requirements, noting the 5 µs delay under minimal overdrive conditions.

Part Context

The ADCMP371 is part of the ADCMP370/ADCMP371 family of general-purpose comparators from Analog Devices. These devices are designed for low-power, portable applications requiring high input voltage tolerance. The ADCMP371 specifically differentiates itself through its push-pull output structure, contrasting with the open-drain output of the ADCMP370. Both share identical input characteristics and packaging options.

Replacement Considerations

The ADCMP370AKSZ-REEL7 serves as a functional alternative if an open-drain output with external pull-up is acceptable. Verify pinout compatibility and ensure the replacement supports the required 22 V input tolerance. Check that the thermal impedance and package dimensions remain consistent for existing PCB layouts.
