ADS8509: Recommended sequence

Part Number: ADS8509

Hi team,

Could you give me comment on following customer question?

Q1. Does ADS8509 have recommended sequence from start up?

Now the customer accesses the device "without SYNC". But, the first access from the start up responds "with SYNC". The second, third, ..., access respond "without SYNC" as expected. The customer wants to get the first access "without SYNC" as expected. That's why they're asking above question. 

Best regards,

Takeshi Sasaki

    Hello, 

    Can you explain what you mean by "without SYNC"  I am assuming that they are referring to the SYNC pin of the device, but I would like to be sure I understand what they are doing.

    Also, it is important to note that the first conversion immediately following a power-up does not produce a valid conversion result.

    Regards, Cynthia
