Voltage ADC
The IC implements a multichannel, fully differential 10-bit ADC for internal and external voltage measurements.
The ADC supports the following 7 inputs:
•
PS, PF, PR, PGND, used for on-demand conversions and by the diagnostic routine
•
VRCM, used by the diagnostic routine
•
ERBST, used for on-demand conversions and by the diagnostic routine
•
GND, used for on-demand conversions and by the diagnostic routine
The ADC is designed to convert any of the following 7 paths:
•
PS vs PGND
•
PF vs PGND
•
PR vs PGND
•
PF vs PR in high resolution (pre-deployment), with IPF_PU and IPR_PD enabled
•
PF vs PR in low resolution (post deployment), with IPF_PU and IPR_PD enabled
•
ERBST vs GND
•
VRCM vs GND (VRCM enabled)
The ADC conversion formula is the following:
VADC=LSB×CODE
(8)
Where LSB is VADC_LSB_x (according to conversion requested) and CODE is a 10-bit signed word.
