Allegro - Digital position sensor ICs

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.
