The A3425 is a dualoutput-channel, bipolar Switch with each channel comprising a separate complete Hall-effect Sensor circuit with dedicated Hall element and separate digital output for speed and direction signal processing capability. The independent Hall elements (E1 integrated with OUTPUTA, and E2 integrated with OUTPUTB) are photolithographica

lly aligned to better than 1 m. Maintaining this accurate mechanical location between the two active Hall elements eliminates the major manufacturing hurdle encountered in fine-pitch detection applications. The A3425 is a highly sensitive, temperature-stable magnetic sensing device, which is ideal for use in ring magnet-based speed and direction systems used in harsh automotive and industrial environments.
