MAX9077ESA-T

Overview

The MAX9077ESA-T is a dual analog comparator from Analog Devices Inc./Maxim Integrated, housed in an 8-pin SO package. It operates on a single supply voltage ranging from 2.1V to 5.5V with a typical supply current of 3µA per comparator. The device features a propagation delay of 580ns and supports ground-sensing inputs within a common-mode range of -0.2V to VCC-1.2V. It provides rail-to-rail push-pull outputs capable of driving loads up to 2mA without phase inversion.

Feature Summary

• Ultra-low power consumption of 3µA per comparator enables extended battery life in portable applications.
• Rail-to-rail output swing with large internal drivers allows direct interface with TTL/CMOS logic.
• Ground-sensing inputs allow operation down to 0V common-mode voltage without phase inversion.
• No differential clamp across inputs permits full rail-to-rail differential input voltage range.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging configuration. Confirm the 'ESA' designation corresponds to the 8-pin SO package variant. Ensure compatibility with industrial temperature ranges (-40°C to +85°C) for your specific application environment before finalizing procurement.

Selection Notes

Select this component when low power consumption is critical alongside small footprint requirements. The dual-channel configuration suits applications requiring two independent comparison functions. Verify that the 580ns propagation delay meets system timing constraints. Ensure the 2mA output drive capability is sufficient for the connected load impedance.

Part Context

This part belongs to the MAX9075/MAX9077 family of low-cost, ultra-small single-supply comparators. The MAX9077 specifically denotes the dual-channel version, contrasting with the single-channel MAX9075. The family is optimized for 3V and 5V systems, offering a balance of speed and power efficiency for portable electronics.
