A1230 - Allegro

A1230 Ultra-Sensitive Dual-Channel Quadrature Hall-Effect Bipolar Switch

The A1230 is a dual-channel, bipolar switch with two Halleffect sensing elements, each providing a separate digital output for speed and direction signal processing capability. The Hall elements are photolithographically aligned to better than 1 µm. Maintaining accurate mechanical location between the two active Hall elements eliminates the major manufacturi.
