AK8779A

[AK8779A] AK8779A Hall Effect IC for Pulse Encoders 1. General Description The AK8779A is a Hall effect latch which detects both “vertical magnetic field” and “horizontal magnetic field” (perpendicular and parallel to the marked side of the package) at the same time. The pulse output F and the 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 on a rising or falling edge of output F. The AK8779A is for use in the incremental pulse encoders or rotational detection systems.  Supply Voltage:  Operation Temperature:  Sensitivity (Vertical):  Sensitivity (Horizontal):  Two Outputs:  Package: 2.
