MAX9094AUD+

Overview

The MAX9094AUD+ is a quad, low-voltage comparator from the MAX909x family. It operates on a single supply voltage ranging from +1.8V to +5.5V and features open-drain outputs. The device provides a typical propagation delay of 100ns and includes input common-mode voltage range that extends to ground. It supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Quad configuration with four independent comparators in a compact package
• Open-drain output structure for flexible logic interfacing
• 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 electronic devices
• General-purpose portable electronics

Procurement Notes

Verify the specific suffix AUD+ corresponds to the 14-pin TSSOP package and lead-free/RoHS compliance status as defined in the manufacturer's ordering information. Confirm the device meets the required -40°C to +125°C automotive-grade temperature specifications before integration into final designs.

Selection Notes

Select this component when a quad comparator topology is required within space-constrained mobile or battery-operated applications. It serves as a pin-for-pin compatible replacement for legacy LMX393H devices. Ensure the design accommodates open-drain outputs requiring external pull-up resistors.
