HAL855
DATA SHEET
Digital Output
Slew Rate
This 12-bit register delivers the actual digital value of
the applied magnetic field after the signal processing.
This register can only be read out, and it is the basis
for the calibration procedure of the sensor in the sys-
tem environment.
The SLEW RATE register is a “sub”-register of the
CURRENTSOURCE register. The output fall time of
the HAL855 depends on the SLEW RATE register set-
ting and the external load circuit.
Note: The output rise time is purely due to the external
load and is not controlled by the SLEW RATE
register.
Offset Correction
The OFFSET CORRECTION register allows to adjust
the digital offset of the built-in A/D-converter. The digi-
tal offset can be programmed to −3/4, −1/2, −1/4, 0,
+1/4, +1/2, +3/4 of full-scale.
