AS5510 − Electrical Characteristics

Note(s) and/or Footnote(s):

1. Offsetinp = 0.35mT residual offset + 0.1mT earth magnetic field.

2. Linearity error =

3. This time is needed for the first power-up of the device until the offset compensation is finished; Includes readout of the PPROM

fuses; It depends on the sensitivity setting.

4. Time after switching from power-down mode into active mode until the offset compensation is finished.

5. Input related Noise (NoiseInp) is the repeatability of the measurement.
