AK8779B
Hall Effect IC for Pulse Encoders
1. General Description
The AK8779B is a Hall effect latch which detects both “vertical” and “horizontal” (perpendicular and
parallel to the marked side of the package) magnetic fields at the same time. The OUTA and OUTB
outputs are switched according to the vertical and horizontal magnetic fields applied to the device. The
AK8779B is for use in the incremental pulse encoders or rotational detection systems.
