MAX9030AXT+T

Overview

The MAX9030AXT+T is a low-cost, single-supply analog comparator optimized for portable applications. It operates within a voltage range of +2.5V to +5.5V and consumes 35µA of supply current per comparator across the -40°C to +125°C temperature range. The device features a propagation delay of 188ns and includes an internal 4mV hysteresis to prevent oscillations with slow-moving input signals. It incorporates a shutdown mode that reduces supply current to 0.05µA. The output stage swings rail-to-rail and substantially reduces switching current during transitions to eliminate power-supply glitches.

Feature Summary

• Includes a dedicated shutdown pin to minimize power consumption in standby modes
• Features built-in 4mV hysteresis to ensure noise immunity and stable switching
• Provides rail-to-rail output swing capability for direct logic interfacing
• Designed to virtually eliminate power-supply glitches during output transitions

Applications

• Battery-powered systems
• Portable consumer electronics
• Mobile communications devices
• Sensor signal detection circuits
• Threshold detectors and discriminators

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the selected variant matches the required operating temperature range and pin configuration for your PCB layout.

Selection Notes

Select this component when space constraints require a 6-pin SC70 or SOT23 package. Choose this part if a shutdown feature is necessary to extend battery life in portable designs. Consider alternatives from the same family if dual or quad configurations are required instead of a single channel.

Part Context

This part belongs to the MAX9030/MAX9031/MAX9032/MAX9034 family of ultra-small comparators manufactured by Analog Devices/Maxim Integrated. While the MAX9031 lacks a shutdown pin, the MAX9030 specifically integrates this functionality. The family shares similar electrical characteristics but varies in channel count and physical footprint options.

Replacement Considerations

Direct substitutes include other members of the MAX903x family such as the MAX9031, though it lacks the shutdown pin. Verify pin compatibility and functional equivalence before swapping components.
