Digital position sensor ICs cross-reference guide

Allegro offers a wide range of digital position sensors consisting of Hall-effect switches, latches and other special purpose devices. Over time and with ongoing innovation, the basic architecture of these Hall-effect sensors has evolved from its original form (continuous-time) into today’s modern, chopper-stabilized devices.

This application guide will outline the differences between the two sensor types and provide system designers with the tools needed in order to select the appropriate sensor for their system. A cross-reference table is also provided, which summarizes the suggested replacement device to be used when upgrading from a continuous-time device to a chopper-stabilized device.
