AURIX™ MCU: Differences between VADC and DSADC - KBA234494
Community Translation: AURIX™MCU：VADCとDSADCの違い - KBA234494
VADC (Versatile Analog-to-Digital Converter) is a multi-functionality hardware module that converts analog signals to digital signals with MCU VADC channel pins. See the “Versatile Analog-to-Digital Converter (VADC)” (related to AURIX™ TC2xx devices) and “Enhanced Versatile Analog-to-Digital Converter (EVADC)” (related to AURIX™ TC3xx devices) sections of the user’s manual.
DSADC (Delta-Sigma Analog-to-Digital Converter): It is designed specifically to convert the resolver signal sine and cosine information into a digital representation of input angle and velocity. DSADC comes with built-in on-chip carrier generator which produces a selectable output signal (sine, triangle, rectangle) which can be used to simulate resolver signal. Alternatively, you can configure the synchronization of each DSADC input signal to the carrier signal to compensate the error of angle. See the “Delta-Sigma Analog-to-Digital Converter (DSADC)" (related to AURIX TC2xx devices) and “Enhanced Delta-Sigma Analog-to-Digital Converter (EDSADC)” (related to AURIX™ TC3xx devices) sections of the user’s manual.
