Description

Onechip Encoders
The AK8778B is a Hall effect latch which detects both vertical magnetic field and horizontal magnetic field (perpendicular and parallel to the marking side of the package) at the same time. The pulse output F and direction output D are switched according to the vertical and horizontal magnetic fields applied to the device. The direction is calculated internally and output D is switched at a rising or falling edge of output F. The AK8778B is for use in the incremental pulse encoders or rotational detection systems.
