ADC Measurement Interface

ADC Measurement Interface
The SBC measurement interface comprises a battery measurement unit (high voltage input
V
bat_sense) and an on-
chip temperature sensor. A multiplexer is used to select the desired input channel that is connected to the ADC of
the
μC. This multiplexer is controlled via the SPI interface. Also, the reference voltage V
AREF is provided by the
SBC. The
V
bat_sense input must be protected against voltage transients, like ISO pulses by a resistor in series to
terminal 30.

Voltage Measurement
The input voltage is filtered and scaled down to the input voltage range of the ADC converter. The voltage
measurement output code of the ADC can be calculated using the following equation, where
V
SENS is the voltage
at the pin
V
BAT_SENSE and N the resolution of the ADC:

The input voltage corresponding to the ADC output code
C
VSENS can be calculated with the following equation:

Voltage Measurement Calibration Concept
Best measurement accuracy can be obtained by applying the calibration function:
(3)
C
VSENS represents the ADC output code for the analog input voltage at the pin VBAT_SENSE. The correction
coefficients c1 and c0 correct for slope variations and offset errors of the measurement transfer function.
During the production test these calibration figures are calculated and stored in the flash memory of the
microcontroller.
