Summary
Ultra-Sensitive Dual-Channel Quadrature Hall-Effect Bipolar Switch
Description
The A3425 is a dual–output-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 withOUTPUTB) are photolithographically aligned to better than 1 μm. Maintaining this accurate mechanical location between the two active Hall elements eliminates the major manufacturing hurdle encountered in fine-pitch detection applications.
