Overview
The MAX9093AUA+T is a dual-channel, general-purpose analog comparator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single supply voltage ranging from +1.8V to +5.5V and features an operating temperature range of -40°C to +125°C. The device incorporates internal hysteresis of 2mV for noise immunity and utilizes open-drain outputs. It is housed in an 8-pin uMAX package.
Feature Summary
- Internal 2mV hysteresis provides noise immunity and prevents output oscillations with slow-moving input signals
- Low supply current consumption of approximately 65µA per channel at +5.0V
- Input common-mode voltage range includes ground without phase reversal for overdriven inputs
- Fast propagation delay characteristics with low output saturation voltage
Applications
- Mobile communications systems
- Notebooks and PDAs
- Battery-powered electronics
- General-purpose portable devices
- General-purpose low-voltage applications
Procurement Notes
Verify the specific suffix 'AUA+T' against official documentation to confirm the 8-pin uMAX package and tape-and-reel delivery format. Ensure the component meets RoHS compliance standards as indicated by the '+' designation. Confirm availability status directly with authorized distributors or the manufacturer, as stock levels may vary.
Selection Notes
Select this component when a dual-channel comparator with integrated hysteresis is required for low-voltage operation. It serves as a pin-for-pin compatible replacement for older LMX393H designs. Consider its small footprint and low power profile for space-constrained and battery-operated portable applications.
Part Context
This part belongs to the MAX9092/MAX9093/MAX9094/MAX9095 family of general-purpose, low-voltage comparators. These devices are designed to replace legacy parts like the LMX393 series while offering improved performance metrics such as lower supply current and enhanced noise immunity through built-in hysteresis mechanisms.
Replacement Considerations
The MAX9093AUA+T is documented as a pin-for-pin compatible replacement for the LMX393H.
FAQ
Does the MAX9093AUA+T include internal hysteresis?
Yes, the MAX9093AUA+T features 2mV of internal hysteresis to provide noise immunity and prevent output oscillations.
What is the input common-mode voltage range?
The input common-mode voltage range includes ground, extending from -0.1V below the negative supply to within +0.8V of the positive supply.
