MAX9095ASD+T

Overview

The MAX9095ASD+T is a quad, general-purpose, low-voltage analog comparator manufactured by Analog Devices (Maxim Integrated). 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 2mV hysteresis for noise immunity and provides open-drain outputs with a fast propagation delay of 100ns. It utilizes a 14-pin SOIC package.

Feature Summary

• Internal 2mV hysteresis prevents output oscillations caused by noise or slow-moving input signals
• Open-drain outputs allow flexible interfacing with various logic families
• Input common-mode voltage range includes ground potential
• No phase reversal occurs when inputs are overdriven

Applications

• Mobile communications systems
• Notebooks and personal digital assistants (PDAs)
• Battery-powered electronics
• General-purpose portable devices
• Low-voltage application circuits

Procurement Notes

Verify the specific suffix ASD+T against the manufacturer's current ordering guide to confirm the package type and tape-and-reel quantity. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision date to confirm electrical characteristics match your design specifications before finalizing procurement.

Selection Notes

Select this component when a quad comparator configuration is required in a compact surface-mount package. The internal hysteresis makes it suitable for noisy environments without external feedback components. Verify that the open-drain output architecture aligns with the pull-up resistor requirements of the downstream circuitry. Consider the wide operating temperature range for automotive or industrial applications.

Part Context

This part belongs to the MAX909x family of low-cost, general-purpose comparators. It is pin-for-pin compatible with legacy parts like the LMX339H but offers improved performance in low-voltage operation. The quad configuration distinguishes it from the dual-channel MAX9093, providing four independent comparison channels in a single 14-pin package.

Replacement Considerations

The MAX9095ASD+ serves as a direct replacement for the LMX339H in existing designs due to pin compatibility. When substituting, ensure the new part supports the required supply voltage range and that the open-drain output interface matches the original circuit's pull-up configuration.
