ADS7280: VREF for 5V input range

Nick

Part Number: ADS7280

Tool/software:

Hello 

I am planning to use Dual channel ADS7280 for input voltage range from 0 to 5V. Please suggest the VREF for same ADC. 

 I looked at ADC-Voltage Reference Selection Tool. But It doesn't recommend VRef 5V. why so? As per datasheet, Absolute max rating  is 7 V.

    Hi Nick,

    Thanks for the question. The reference selection tool seems to be parsing the voltage level data incorrectly. You may use a precision 5V reference like the REF5050. Please follow the guidance in the datasheet regarding decoupling capacitors:

    Best regards,
