General Description AS5304/AS5306 Integrated Hall ICs for Linear and Off-Axis Rotary Motion Detection The AS5304/AS5306 are single-chip ICs with integrated Hall elements for measuring linear or rotary motion using multi-pole magnetic strips or rings. This allows the usage of the AS5304/AS5306 in applications where the Sensor IC cannot be mounted at the end of a rotating device (e.g. at hollow shafts). Instead, the AS5304/AS5306 are mounted off-axis underneath a multi-pole magnetized ring or strip and provides a quadrature incremental output with 40 pulses per pole period at speeds of up to 20 meters/second (AS5304) or 12 meters/second (AS5306). A single index pulse is generated once for every pole pair at the Index output.
