Reference voltage
Equivalent fixed internal reference(voltage scaling enabled)

For best accuracy, the ADC conversion should be initiated
through the TI-RTOS API in order to include the gain/offset
compensation factors stored in FCFG1.

For best accuracy, the ADC conversion should be initiated
through the TI-RTOS API in order to include the gain/offset
compensation factors stored in FCFG1. This value is derived
from the scaled value (4.3 V) as follows:
V
