Maxim Integrated MAX44268 Low-Power Dual Comparator Datasheet
The MAX44268 is a general‑purpose dual comparator designed for battery‑powered devices where board space and power consumption are critical. It operates from 1.8 V to 5.5 V supply rails, draws only 0.7 µA per comparator, and includes an internal 1.236 V ±1 % reference. Its open‑drain outputs and rail‑to‑rail input structure make it suitable for smartphones, notebooks, portable medical equipment, and other ultra‑low‑power applications.
The datasheet provides detailed electrical characteristics such as a typical input offset voltage of 5 mV, input bias current of 0.15 nA, and operation over a temperature range of –40 °C to +85 °C. Mechanical information lists the 1.3 mm × 1.3 mm, 9‑bump WLP package, and guidelines for board layout and bypassing. Typical application circuits illustrate window‑detector and jack‑detect implementations.
