The ADC conversion rate is tied to the modulator clock derived from the internal oscillator. The product status is Active. ## What the dual 24-bit ADC means for the BOM Two 24-bit sigma-delta converters on a single die eliminate an external ADC and the associated SPI isolator or level shifter. Each channel can be configured for differential inputs, which pairs directly with a shunt or a current transformer in a power-monitoring front end. The 11 general-purpose I/O are enough to drive a small LCD segment, a few LEDs, and a pushbutton, but not a parallel bus or a key matrix—plan the pin allocation before layout.","metaTitle":"TI MSP430AFE252IPW 16-bit MCU, 12 MHz, 16 KB Flash, 24-bit ADC","metaDescription":"Texas Instruments MSP430AFE252IPW 16-bit MCU, 12 MHz core, 16 KB Flash, 512 B RAM, dual 24-bit sigma-delta ADC, SPI/UART, 24-TSSOP, -40°C to 85°C.
