Product details

110ns propagation delay — where it fits in the signal chain

The MAX9092AUA+: The 110ns figure is the max at 5V — at 3.3V the delay stretches, so budget margin if the downstream logic expects a 100ns window. The open-drain output lets you wire-OR multiple comparators or pull up to a different rail than the supply. Quiescent current maxes at 200µA per channel (400µA total for both), which puts it in the low-power zone for battery-operated threshold detection. Input bias current is 0.25µA max at 5V — high enough that a 10MΩ source impedance drops 2.5V across the bias, so keep the source impedance below 100kΩ for the offset to stay within the 7mV input offset spec.

Temperature grade and supply flexibility

The tube packaging is the standard delivery — if you need tape-and-reel for automated assembly, confirm the reel option with the supplier at RFQ, as the MAX9092AUA+ is listed in tube only.

Frequently asked questions

Can the MAX9092AUA+ replace an LM393 directly?

Not pin-for-pin. The LM393 uses an 8-DIP or SOIC-8 footprint; the MAX9092AUA+ comes in the smaller 8-uMAX/uSOP package (3.00mm body width). Both are dual comparators with open-drain outputs and similar supply ranges, but the pinout differs — the MAX9092AUA+ follows the Maxim/uMAX pin arrangement. A board layout change is required. Electrically, the 110ns propagation delay of the MAX9092AUA+ is significantly faster than the LM393's typical 1.3µs, so timing margins improve if the signal path can tolerate the faster edges.

Is the MAX9092AUA+ suitable for low-power applications?

Yes. The quiescent current is 200µA max per comparator (400µA total for both channels), which is low enough for battery-powered threshold detectors, window comparators, and wake-up circuits.
