I'm considering to use MSP432 for my research.

I have a confustion about ADC size.

In ref. manual it has 14 bit.

However, in datasheet and the other website such as Digi-Key say it has 16 bit.

Which one is correct?

Khungin,

The precision ADC is a 14-bit ADC, but the ENOB (equivalent number of bits), which is a reflection of internal noise & distortion, is so low that a 16-bit conversion can be performed using oversampling.

To learn more about how to use oversampling, see the TI App Notes listed below:

General Oversampling of MSP ADCs for Higher Resolution (SLAA694A)
The secret of using noise to improve your ADC’s performance (TI Blog)

You can also see oversampling referenced in our MSP432 Product home page.
