Overview
The MAX9077EKA-T is a dual, low-cost, ultra-small single-supply comparator from Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.1V to 5.5V and consumes only 3µA per comparator. The device features a propagation delay of 580ns and supports rail-to-rail outputs with up to 2mA drive capability. It utilizes an 8-pin SOT23 package and functions 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 inputs without differential clamping
- 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 ordering suffix EKA+T against official Maxim Integrated documentation to confirm the 8-pin SOT23 package and tape-and-reel delivery format. Ensure compatibility with the required -40°C to +85°C industrial temperature range and lead-free/RoHS compliance standards before finalizing procurement specifications.
Selection Notes
Select this component when space constraints require an 8-pin SOT23 footprint for dual comparators. It is suitable for designs needing ground-sensing inputs and rail-to-rail outputs in portable applications. Verify that the 580ns propagation delay meets system timing requirements and that the 2.1V minimum supply voltage aligns with the battery or power source characteristics.
Part Context
This part belongs to the MAX9075/MAX9077 family of low-power single-supply comparators. While the MAX9075 provides a single channel, the MAX9077 integrates two channels into a compact form factor. The series is designed for portable electronics requiring minimal quiescent current and fast response times within a restricted voltage window.
Replacement Considerations
The MAX9075EXK+T serves as a functional substitute if a single-channel configuration is acceptable. For dual-channel replacements, verify pinout compatibility between the 8-pin SOT23 packages and ensure equivalent electrical parameters such as supply current and propagation delay are met.
FAQ
Does the MAX9077 support input voltages below ground?
Yes, the common-mode input voltage range extends down to -0.2V, allowing for ground-sensing capabilities.
What is the maximum load current the output can drive?
The internal push-pull output drivers can sink and source up to 2mA while maintaining rail-to-rail swing.
