Overview
The MAX9093AUA+ is a dual, 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 an automotive temperature range of -40°C to +125°C. The device includes internal hysteresis of 2mV for noise immunity and provides open-drain outputs with a propagation delay of approximately 100ns. It consumes low supply current, typically 65µA per channel at +5.0V, and is housed in an 8-pin µMAX package.
Feature Summary
- Internal 2mV hysteresis prevents output oscillations caused by noise or slow-moving input signals
- Low supply current consumption suitable for battery-powered applications
- Open-drain outputs allow flexible interfacing with various logic levels
- Wide operating temperature range supports automotive and industrial environments
Applications
- Mobile communications devices
- Notebooks and PDAs
- Battery-powered electronics
- General-purpose portable devices
- General-purpose low-voltage applications
Procurement Notes
Verify the specific ordering suffix 'AUA+' corresponds to the 8-pin µMAX package and lead-free/RoHS compliance status as defined in the manufacturer's documentation. Confirm that the component meets the required environmental specifications for your intended application before procurement.
Selection Notes
Select this component when a dual comparator with built-in hysteresis is required to ensure signal integrity in noisy environments. It serves as a pin-for-pin compatible replacement for legacy LMX393H devices. Consider the open-drain output configuration and low supply current requirements when designing the circuit.
Part Context
This part belongs to the MAX909x series of general-purpose, low-voltage comparators. The series includes dual (MAX9092/MAX9093) and quad (MAX9094/MAX9095) variants. The MAX9093 variant specifically adds internal hysteresis compared to the MAX9092, enhancing performance in noisy conditions without external components.
Replacement Considerations
The datasheet identifies the MAX9093AUA+ as a pin-for-pin compatible replacement for the LMX393H. Verify compatibility with existing board layouts and electrical characteristics if substituting older components.
