MAX9077EKA

Overview

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

Feature Summary

• Ultra-small footprint suitable for portable applications
• Low-power operation with 3µA consumption per comparator
• Ground-sensing input capability
• Rail-to-rail output swing

Applications

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

Procurement Notes

Verify the specific suffix 'EKA' against official datasheets to confirm the 8-pin SOT-23 packaging and tape-and-reel availability. Confirm RoHS compliance status and lead times directly with authorized distributors or Analog Devices, as availability may vary by region.

Selection Notes

Select this component for designs requiring minimal power consumption and small board space. Ensure the application voltage stays within the 2.1V to 5.5V range. Consider the 580ns propagation delay when designing high-speed signal paths.

Part Context

This part belongs to the MAX907x family of low-cost, ultra-small, single-supply comparators. It shares functional similarities with the MAX9075 (single) and other variants but is distinguished by its dual-channel configuration and specific SOT-23 packaging.

Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX9077ESA or MAX9077EUA if different packaging is required. Verify electrical parameters match before substitution.
