Overview
The MAX9077ESA+ is a dual, low-cost, ultra-small single-supply comparator from Analog Devices/Maxim Integrated. It operates on a single supply voltage ranging from 2.1V to 5.5V and consumes only 3µA per comparator. The device features a propagation delay of 580ns and offers rail-to-rail outputs capable of driving loads up to 2mA. It includes ground-sensing inputs with a common-mode range extending to -0.2V and lacks differential clamping across inputs.
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 8-pin SO package variant when sourcing. Confirm RoHS compliance status via the '+' designation in the ordering information. Ensure the operating temperature range aligns with industrial specifications (-40°C to +85°C). Cross-reference pin configurations to distinguish between SOT23, µMAX, and SO packages within the MAX9077 family.
Selection Notes
Select this component for portable applications requiring minimal footprint and low quiescent current. The dual-channel configuration allows for cost-effective implementation of multiple threshold detection circuits. Verify that the 580ns propagation delay meets system timing requirements. Consider the rail-to-rail output swing for direct interface with TTL or CMOS logic without additional level shifting components.
Part Context
The MAX9077 is part of the MAX9075/MAX9077 family of comparators designed for 3V and 5V single-supply environments. While the MAX9075 provides a single channel, the MAX9077 integrates two comparators into one package. This family emphasizes low power and small size, making it suitable for space-constrained portable electronics where battery life is critical.
Replacement Considerations
The MAX9077EUA+ serves as an alternative in the µMAX package. The MAX9077MSA/PR2 is available for military temperature ranges (-55°C to +125°C). Verify pin compatibility before substituting with other Maxim comparator models.
FAQ
Does the MAX9077 have differential clamping across its inputs?
No, unlike many comparators, the MAX9077 does not have a differential clamp across the inputs, allowing the differential input voltage range to extend rail-to-rail.
What is the maximum load current the output can drive?
The large internal push-pull output drivers allow rail-to-rail output swing with loads up to 2mA.
Can the inputs sense ground potential?
Yes, the device features ground-sensing inputs with a common-mode voltage range that extends down to -0.2V.
