2.1 Best-in-Class 12-Bit ADC Integrated

The MSPM0 ADC provides best-in-class ENOB and SNR performance of any ADC in its MCU class. The ADC provides 12-bit 4-Msps sampling and 14-bit 250-ksps averaged sampling on MSPM0G devices and 12-bit 1.45-Msps sampling on MSPM0L devices. The hardware averaging feature is able to increase the effective resolution of the ADC without the need for software and CPU intervention. The ADC also operates at these high speeds in low-power modes with fast wakeup times. The ADC signals that can be sampled directly from onboard OPA, DACs, temperature sensors, and up to 16 external input channels. The reference voltage can be connected to VDD, an external reference, or internal references. Configurable 12-, 10-, and 8-bit resolutions also support faster sampling rates. #FIG_PRZ_FJP_VVB shows the key attributes of the MSPM0 ADC.
