The MAX44269 is the industry's smallest dual comparator, featuring ultra-low power consumption and a compact package ideal for battery-powered applications such as cell phones, notebooks and portable medical devices that have extremely aggressive board space and power constraints.
The MAX44269 dual comparator is designed for battery‑powered devices where board space and power consumption are critical. It is offered in a miniature 1.3 mm × 1.3 mm 9‑bump WLP package, the industry’s smallest dual comparator, and features rail‑to‑rail inputs, open‑drain outputs, internal filtering, and a 4 mV hysteresis. Typical applications include smartphones, notebooks, portable medical equipment, and other ultra‑low‑power systems. The device operates from 1.8 V to 5.5 V, draws only 0.5 µA per comparator, and works over a temperature range of –40 °C to +85 °C.
