(1)
The external reference is used during ADC conversion to charge and discharge the capacitance array. The input capacitance, CI, is also
the dynamic load for an external reference during conversion. The dynamic impedance of the reference supply should follow the
recommendations on analog-source impedance to allow the charge to settle for 12-bit accuracy.
(2)
The accuracy limits the minimum positive external reference voltage. Lower reference voltage levels may be applied with reduced
accuracy requirements.
(3)
The accuracy limits the maximum negative external reference voltage. Higher reference voltage levels may be applied with reduced
accuracy requirements.
(4)
The accuracy limits minimum external differential reference voltage. Lower differential reference voltage levels may be applied with
reduced accuracy requirements.
(5)
Two decoupling capacitors, 10
F and 100 nF, should be connected to VEREF to decouple the dynamic current required for an external
reference source if it is used for the ADC10_A. See also the MSP430x5xx/MSP430x6xx Family User
's Guide (SLAU208).
