MAX9077EKA/GH9-T

Overview

The MAX9077EKA/GH9-T is a dual analog comparator from Analog Devices Inc./Maxim Integrated, optimized for single-supply operation. It features a propagation delay of 580ns and consumes only 3µA per comparator. The device operates on a single supply voltage ranging from 2.1V to 5.5V. It includes ground-sensing inputs and rail-to-rail outputs without output phase inversion for overdriven inputs. The component is housed in an ultra-small 8-pin SOT-23 package.

Feature Summary

• Ultra-low power consumption of 3µA per comparator
• Ground-sensing input capability
• Rail-to-rail output swing
• No output phase inversion for overdriven inputs

Applications

• Battery-powered systems
• Threshold detectors/discriminators
• Keyless entry systems
• IR receivers
• Digital line receivers

Procurement Notes

Verify the specific suffix GH9 against official manufacturer documentation to confirm tape-and-reel packaging specifications and lot traceability requirements. Ensure compatibility with standard surface-mount reflow profiles for the SOT-23 package. Confirm RoHS compliance status through current datasheets or environmental reports prior to procurement.

Selection Notes

Select this component for portable applications requiring low power and small footprint. The dual configuration offers two comparators in one package. Verify that the 580ns propagation delay meets system timing requirements. Ensure the 2.1V minimum supply voltage aligns with the battery discharge curve of the target application.

Part Context

This part belongs to the MAX907x family of low-cost, ultra-small, single-supply comparators. The MAX9075 provides a single comparator, while the MAX9077 provides dual comparators. Both share similar electrical characteristics but differ in pin count and package options, such as SC70 and SOT-23.

Replacement Considerations

Check for direct substitutes within the MAX907x series, such as the MAX9075 for single-channel needs. Verify pinout compatibility if replacing with other dual comparators in SOT-23 packages. Ensure equivalent propagation delay and supply voltage ranges are met by alternative parts.
