Internal 4.3-V equivalent reference⁽²⁾
VDDS as reference
Equivalent fixed internal reference (input voltage scaling
enabled). For best accuracy, the ADC conversion should
be initiated through the TI-RTOS API to include the
gain/offset compensation factors stored in FCFG1.
Fixed internal reference (input-voltage scaling disabled).
For the best accuracy, the ADC conversion should be
initiated through the TI-RTOS API to include the gain/offset
compensation factors stored in FCFG1. This value is
derived from the scaled value (4.3 V) as follows.
V_ref = 4.3 V × 1408 / 4095

200 ksps, voltage scaling enabled. Capacitive input, input
impedance depends on sampling frequency and sampling
time
(5) Applied voltage must be within absolute maximum ratings at all times (see Section 5.1).
