MAX9077ESA+

Overview

The MAX9077ESA+ is a dual analog comparator optimized for single-supply operation within a voltage range of 2.1V to 5.5V. It features a propagation delay of 580ns and consumes only 3µA per channel. The device utilizes an 8-pin SO package and supports rail-to-rail inputs and outputs with a common-mode input range extending from -0.2V to VCC-1.2V. It operates reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low power consumption of 3µA per comparator
• Rail-to-rail push-pull output drivers
• Ground-sensing input capability
• 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 'ESA+' corresponds to the lead-free, RoHS-compliant 8-pin SO package variant. Confirm that the operating temperature range matches the required industrial specification (-40°C to +85°C). Ensure the ordering information aligns with the manufacturer's current datasheet revision to avoid discrepancies in pinout or electrical characteristics.

Selection Notes

Select this component when low quiescent current is critical alongside high-speed response. The dual-channel configuration allows for cost-effective implementation of multiple threshold detection circuits. Verify that the load requirements do not exceed the 2mA drive capability of the internal push-pull output stage.

Part Context

This part belongs to the MAX9075/MAX9077 family of low-cost, ultra-small comparators designed for portable applications. While the MAX9075 provides a single channel, the MAX9077 integrates two channels into a compact footprint. The series is engineered to minimize power consumption while maintaining fast switching speeds suitable for battery-operated devices.
