MAX9094ASD+

Overview

The MAX9094ASD+ is a quad, 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 provides a propagation delay of 100ns and draws approximately 65µA per channel at +5.0V. It includes input common-mode voltage range extending to ground and ensures no phase reversal for overdriven inputs.

Feature Summary

• Quad configuration with low supply current consumption
• Open-drain output structure compatible with various logic levels
• Input common-mode voltage range extends to ground without phase reversal

Applications

• Mobile communications systems
• Notebooks and PDAs
• Battery-powered electronics
• General-purpose portable devices

Procurement Notes

Verify the specific package type (SOIC-14) and temperature grade (A-grade: -40°C to +125°C) against project requirements. Confirm that the open-drain output architecture aligns with the system's pull-up resistor design. Ensure the component meets all relevant environmental compliance standards required for the final assembly.

Selection Notes

Select this component when a quad comparator is needed in a small footprint. It serves as a pin-for-pin replacement for older LMX339 equivalents. Consider the 100ns response time and low power profile for battery-operated applications requiring multiple comparison functions within a limited board area.

Part Context

This part belongs to the MAX909x family of low-voltage comparators. The series includes dual (MAX9092/MAX9093) and quad (MAX9094/MAX9095) variants. The MAX9094 specifically offers four independent channels in a 14-pin SO package, designed for cost-sensitive and space-constrained portable electronic designs.

Replacement Considerations

The datasheet identifies the MAX9094 as a pin-for-pin compatible replacement for the LMX339.
