5.10.15 Smart Analog Combo (SAC) (MSP430FR235x Devices Only)

The MSP430FR235x devices integrate four SAC modules: SAC0, SAC1, SAC2, and SAC3. The SAC integrates a high-performance low-power operational amplifier. SAC-L3 supports a hybrid configuration of general-purpose amplifier, 12-bit voltage reference DAC, and a multiplex switch array. For more information, see the SAC chapter in the MSP430FR4xx and MSP430FR2xx Family User's Guide. Only MSP430FR235x devices implement the SAC modules. MSP430FR215x devices do not support SAC modules.

The SAC0 and SAC2 are interconnected and support external inputs and internal inputs (see Table 5-27 and Table 5-28).

Each SAC DAC supports two selectable voltage references (see Table 5-31).
