220ns, 12µA, 6-Bump WLP Comparators with Shutdown

Micropower Comparators in Ultra-Tiny, 1.1 x 0.73mm, 6-bump WLP and SOT23 Packages


Please check latest availability status for a specific part variant.

Description

The MAX40008/MAX40009 are single micropower comparators featuring low-voltage operation and rail-to-rail inputs. Their operating supply voltage range from 1.7V to 5.5V, which makes them ideal for systems running from nominal 1.8V to 5V supplies.

While only consuming 12µA of supply current, the MAX40008/MAX40009 achieve a 220ns propagation delay. These devices feature 0.5mV (typ) input offset voltage and internal hysteresis, ensuring clean output switching, even with slow-moving input signals.

The output stage’s unique design limits supply-current surges while switching, virtually eliminating the supply glitches typical of many other comparators. The MAX40009 has a push-pull output stage, while the MAX40008 has an open-drain output stage that can be pulled beyond VDD to 6V (max) above GND input. The open-drain version is ideal for level translators and bipolar to single-ended converters.

The MAX40008/MAX40009 are available in tiny 0.73mm x 1.1mm 6-bump wafer-level packages (WLPs), significantly reducing the required board area. An alternative 6-pin SOT23 package is also available. These devices are fully specified over the -40°C to +125°C automotive temperature range.
