[AK8778] AK8778 Hall Effect IC for Pulse Encoders Overview The AK8778 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 AK8778 is for use in the incremental pulse encoders or rotational detection systems. Features       4.0 to 24V supply voltage operation Low power consumption : 1.4mA(Typ.) Sensitivity (Vertical, Horizontal) : ±2.5mT(Typ.
