What is the output polarity of Allegro devices?
Single-element circuits are designed to have a fixed output polarity (high over a tooth or high over a valley, depending on the specific device). Refer to data sheets to determine the actual polarity of a given single-element product. Differential circuits can be high over a tooth or high over a valley depending solely on target rotation direction. Refer to data sheets to determine the rotation/polarity convention for a given differential product.
