We have some quesions for VREFHI of ADC on TMS320F28377D-EP.
We would really appreciate it, if you would confirm our questions.
1.In Table 4-41 in the datasheet, VREFHI is 2.4V as MIN, 2.5 or 3.0V as TYP and VDDA as MAX.
Though we would set VDDA to 3.3V, can we set VREFHI to 3.3V?
Also, would you please tell me any design precautions?
2.It seems VREFHI is assigned 3.0V on the evaluation board.
Could you tell us the reason why VREFHI is 3.0V not 3.3V?
