AK8776
Hall IC for Pulse Encoder
Overview
AK8776 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 and outputs the pulse (F) and rotational direction (D).
AK8776 is for use in portable devices which uses rotational detection system or incremental pulse encoder such as
jog dial utilized for input devices.
Features
o 1.6 to 5.5V operation
o Bop, Brp(Vertical, Horizontal) ±1.5mT(Typ.), Highly sensitive
o Low power operation : Average 90μA(Typ.) @V_DD=3V
o Two Output: F-Output (Pulse count), D-Output (Direction of rotation)
o Small package: SOP-4pin, Halogen free
