Frequently Asked Questions

How low is the supply current of the MAX9018AEKA+, and why does it matter for battery-powered designs?

The MAX9018AEKA+ is a nanoPower comparator with an input bias current as low as 0.001 µA at 25°C, enabling extremely long battery life in always-on sensing and threshold-detection circuits running from coin cells or energy harvesters.

Can the MAX9018AEKA+ operate from a 1.8 V single supply used in modern microcontroller systems?

Yes, the MAX9018AEKA+ is specified for 1.8 V single-supply operation, making it directly compatible with low-voltage MCU platforms and LDO-regulated rails without an additional supply boost stage.

What package and pin count does the MAX9018AEKA+ use, and how does it benefit compact PCB layouts?

The MAX9018AEKA+ is housed in an 8-pin SOT-23 package, which has a very small footprint and allows both comparator channels plus supply and reference pins to fit into space-constrained wearable or portable device PCBs.

When should a designer choose the MAX9018AEKA+ with an internal reference over an external-reference variant?

Choosing the MAX9018AEKA+ with an internal reference saves one external component and simplifies BOM management in designs where a fixed threshold is acceptable, such as battery undervoltage lockout at a defined threshold below 1.8 V.
