Overview
The MAX9092AUA+ is a dual-channel general-purpose analog comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from +1.8V to +5.5V and features open-drain outputs. The device guarantees performance across an extended temperature range of -40°C to +125°C. Key electrical specifications include a maximum input offset voltage of 7mV, a propagation delay of approximately 100ns, and a low supply current consumption of roughly 65µA per channel at 5.0V. It utilizes an 8-pin µMAX package.
Feature Summary
- Pin-for-pin compatible replacement for LMX393/LMX393H comparators
- Low supply current consumption optimized for battery-powered applications
- Input common-mode voltage range includes ground potential
- No phase reversal occurs when inputs are overdriven
Applications
- Mobile communications equipment
- Notebooks and personal digital assistants (PDAs)
- Battery-powered electronics
- General-purpose portable devices
- General-purpose low-voltage applications
Procurement Notes
Verify the specific ordering suffix to confirm the package type matches the design requirements. Ensure the component meets RoHS compliance standards if required by the manufacturing process. Confirm that the operating temperature range aligns with the environmental conditions of the final assembly. Cross-reference the datasheet revision to ensure all electrical characteristics match the intended application parameters.
Selection Notes
Select this component for designs requiring low-voltage operation and small footprint integration. The open-drain output configuration requires an external pull-up resistor to function correctly. Consider the propagation delay and input offset voltage when designing circuits sensitive to timing or precision thresholds. Verify that the load connected to the output does not exceed the specified sink current limits.
Part Context
This part belongs to the MAX9092/MAX9093/MAX9094/MAX9095 family of general-purpose, low-voltage comparators. These devices are designed as direct replacements for industry-standard LMX393 and LMX339 parts. The family offers various configurations including dual and quad channels in tiny packages like SOT23, µMAX, TSSOP, and SO.
Replacement Considerations
The MAX9092AUA+ serves as a pin-for-pin compatible replacement for the LMX393 and LMX393H comparators.
