The AH70X / AH71X is  a speed&direction Hall sensor family with two Hall sensing elements. It outputs two digital signals for speed and direction processing .

 The AH70X/ AH71X internally includes two Hall sensing elements located 1.63mm apart, an on-chip Hall voltage generator, voltage regulator for operation with supply voltage 3.8 to 30V, temperature  compensation circuitry, small-signal amplifier, Hall sensor with dynamic offset cancellation system, Schmitt trigger and open-drain output. Signal processing of speed and direction signals is easy.

  The AH70X/ AH71X family provides a variety of packages to customers: flat TO-94 for through-hole mount and SOP8  for surface mount.  All packages are RoHS compliant.
