Overview
The MAX9030AXT+T is a low-cost, ultra-small single-supply comparator optimized for portable applications. It operates from +2.5V to +5.5V and consumes 35µA per comparator over the -40°C to +125°C temperature range. The device features a 188ns propagation delay, 4mV built-in hysteresis, and rail-to-rail output swing. It includes a shutdown mode that reduces supply current to 0.05µA. Available in space-saving 6-pin SC70 packages.
Feature Summary
- Low-power operation with 35µA supply current
- Built-in 4mV hysteresis for noise immunity
- Shutdown mode for extended battery life
- Rail-to-rail output voltage swing
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 '+T' indicates tape and reel packaging when sourcing components. Confirm the 'A' designation aligns with the required industrial temperature range of -40°C to +125°C. Ensure compatibility with the 6-pin SC70 footprint during PCB layout. Cross-reference the manufacturer's latest datasheet revision for any updates to absolute maximum ratings or electrical characteristics before finalizing procurement.
Selection Notes
Select this component for designs requiring minimal power consumption and small physical footprint. The integrated shutdown feature makes it suitable for battery-operated equipment where standby current must be minimized. Verify that the input common-mode range extending to the negative supply meets system requirements. Consider the 188ns propagation delay for timing-sensitive applications compared to faster alternatives.
Part Context
This part belongs to the MAX903x family of comparators, which includes single (MAX9030/MAX9031), dual (MAX9032), and quad (MAX9034) configurations. The family shares similar electrical characteristics but varies in channel count and package options. The MAX9030 specifically integrates a shutdown pin, distinguishing it from the non-shutdown MAX9031 variant within the same package constraints.
Replacement Considerations
The MAX9031 serves as a direct functional substitute if the shutdown capability is not required. Both share identical electrical parameters and package dimensions. Verify that the absence of the SHDN pin does not impact the circuit design. Other family members like the MAX9032 offer dual channels but require different footprints.
