AS5304/AS5306 Integrated Hall IC for linear and off-axis rotary motion detection

Dynamic Non-Linearity (DNL)
The DNL (dynamic non-linearity) describes the non-linearity of the incremental outputs from one step to the next. In an ideal
system, every change of the incremental outputs would occur after exactly one LSB (e.g. 25μm on AS5304). In practice
however, this step size is not ideal, the output state will change after 1LSB +/-DNL. The DNL must be <+/- ? LSB to avoid a
missing code. Consequently, the incremental outputs will change when the magnet movement over the IC is
minimum 0.5 LSB and maximum 1. 5 LSB ’s.

The AO Output
The Analog Output (AO) provides an analog output voltage that represents the Automatic Gain Control (AGC) of the Hall
sensors signal control loop.
This voltage can be used to monitor the magnetic field strength and hence the gap between magnet and chip surface:
?
?
Short distance between magnet and IC → strong magnet ic field → low loop gain → low AO voltage
Long distance between magnet and IC → we ak magnetic field → high loop gain → high AO voltage
