Linnan, Such requirement is normal for a newcomer, but technically it is a big challenge to provide even 14-bit ADC (SAR type), which TI's competitors do not even provide integrated on MCUs (multisampling tricks do not count). The MSP432 is a new and very popular and powerful device. I really don't even use it's huge potential despite I have it in arsenal because I personally stopped by for analog signal processing on slightly slower MCU - MSP430FR5994 , which technically consume 2-4 times less power than MSP432 in non-demanding applications. Situation changes where needs mostly high-performance. 16-bit SAR resolution is practically very precise and very expensive. Designing analog signal chain with SNR more than 60 dB is a big technical and technological challenge. As an example, low voltage electret microphones do not provide SNR higher than 70 dB (in perfect situation) and in most cases they reach up to 55-60 dB. But such signal needs to be amplified with additional noise from op-amp, power rails and so on. So in real situation you will deal with 40-50 dB SNR. Why I write this? Because 12-bit resolution gives up to 74 dB SNR, and even more dynamic range. So, practically, why do you need 16-bit SAR ADC? Choose from something that you can start. If needed, buy cheap 14-bit DAC with voltage buffer separately. And start developing. Regards, Alexey
