TMS320F28377S: ADC with DAC pins resistance

Danilo A.
Mastermind 34720 points

Part Number: TMS320F28377S

Hi Team,

Some pins of TMS320F28377S are shared by ADC and DAC such as ADCINA0/DACOUTA and ADCINA1/DACOUTB. A customer wants to know the input resistance and tolerance of those pins.

Regards,

Danilo

    Danilo,

    Much of this information can be found in the datasheet:

    The Rpd tolerance is expected to be roughly +/- 20%.

    The pin capacitance will also be slightly different from an ADC perspective:
