Overview

AK8776 is a Hall effect latch which detects both “vertical” and “horizontal” (perpendicular and parallel to the marking side of the package) magnetic field at the same time and outputs the pulse (F) and rotational direction (D).

AK8776 is for use in portable devices which uses rotational detection system or incremental pulse encoder such as jog dial utilized for input devices.
