AURIX™ MCU: Can DSADC interface with an external delta-sigma ADC modulator? – KBA234959
On the AURIX™ TC2XX devices, the modulator and demodulator are used together; therefore, delta-sigma analog-to-digital converter (DSADC) does not interface with an external delta-sigma ADC modulator directly.

However, on AURIX™ TC3XX devices, demodulator can be used separately, so enhanced DSADC can interface with an external delta-sigma modulator to get the data stream.
