MAX44269：1.3mm x 1.3mm, Low-Power Dual Comparator

Industry's Smallest Dual Comparator Solution

The MAX44269 is an ultra-small and low-power dual comparator ideal for battery-powered applications such as cell phones, notebooks, and portable medical devices that have extremely aggressive board space and power constraints. The comparator is available in a miniature 1.3mm x 1.3mm, 9-bump WLP package, making it the industry’s smallest dual comparator. The IC can be powered from supply rails as low as 1.8V and up to 5.5V. It requires just 0.5µA of typical supply current per comparator. It has a rail-to-rail input structure and a unique output stage that limits supply current surges while switching. This design also minimizes overall power consumption under dynamic conditions. The IC has open-drain outputs, making it suitable for mixed voltage systems. The IC also features internal filtering to provide high RF immunity. It operates over a -40°C to +85°C temperature range.
