Hall Speed and Direction Sensor - AH712

AH712 is a series of speed and direction sensors with 2 built-in Hall effect elements. Each element provides an independent digital signal output for speed and direction signal processing.

The chip internally includes two Hall sensing elements spaced 1.63mm apart, including Hall voltage generators, a voltage regulator for 3.8~30V supply voltage, temperature compensation circuits, small-signal amplifiers, dynamic offset cancellation system Hall sensors, Schmitt triggers, and open-drain outputs. It is convenient for processing speed and direction signals.

AH712 is available in TO94 and SOP8 packages and complies with RoHS standards.
