MAX9030AXT

Overview

The MAX9030AXT+T is a low-cost, ultra-small single-channel analog comparator from the Maxim Integrated family. It operates on a single supply voltage ranging from 2.5 V to 5.5 V with a typical quiescent current of 55 µA. The device features a push-pull output and offers a response time of 188 ns. Key electrical specifications include an input offset voltage of 1 mV and an input bias current of 8 nA. It is housed in a compact SC-70-6 surface-mount package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Ultra-small footprint suitable for space-constrained designs
• Low power consumption ideal for battery-operated systems
• Push-pull output stage for direct logic interfacing

Applications

• Battery-powered portable electronics
• Threshold detection circuits
• General-purpose signal conditioning

Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SC-70-6 package dimensions align with PCB layout constraints. Check for availability restrictions or limited stock notices from authorized distributors before finalizing procurement plans.

Selection Notes

Select this component for applications requiring minimal board space and low standby current. The 188 ns propagation delay suits general-purpose timing needs but may be insufficient for high-speed data acquisition. Consider the 1 mV offset voltage tolerance when designing precision threshold circuits. Verify that the 55 µA supply current meets system power budget requirements.

Part Context

This part belongs to the MAX9030 series of low-power comparators manufactured by Analog Devices (Maxim Integrated). The series includes dual and quad variants alongside the single-channel MAX9030. These devices are designed to replace larger, higher-power comparator solutions in modern consumer and industrial electronics where size and efficiency are critical design parameters.

Replacement Considerations

Cross-reference with MAX9031AXK+T for identical electrical performance in an SOT-23-5 package. Evaluate MAX903ESA+T for legacy DIP/SOIC form factors with similar speed characteristics.
