2D, Dual-Channel, Ultrasensitive Hall-Effect Latch

The A1262 integrated circuit is an ultrasensitive Hall-effect latch. It features operation with traditional planar magnetic field direction as well as vertical. The dual operation of the planar and vertical Hall elements allows the end user to achieve 90° of phase separation that is inherently independent of magnetic pole spacing. The quadrature outputs of the A1262 allow rotation direction to be determined, such as when sensing a rotating ring-magnet target.
