Overview

[AK8775] AK8775 Hall IC for Pulse Encoder Overview AK8775 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.

The result of Hall effect latch operation in vertical and horizontal magnetic field is read out to OUTA pin and OUTB pin.

AK8775 is for use in portable devices which uses rotational detection system or incremental pulse encoder such as jog dial utilized for input devices.
