AD5592: SPI Interface Format: nSYNC, SDO

Hi AD,

 

We are using an AD5592RBRUZ (TSSOP-16) to provide an integrated ADC and DAC function and wanted to confirm the following aspects of its SPI interface:

 

1. Is an internal pull up provided for the nSYNC pin (#2) - the Data Sheet is silent, but our assumption is that no internal pull up is provided?

 

2. Is the SDO pin (#9) tri-stated (high impedance) when the nSYNC pin (#2) is in a High (Inactive) state - the Data Sheet (page 6) suggests the SDO pin has a Floating State consistent with a tri-state output format and our assumption is that a tri-state function is implemented?

 

Thank you for your follow up and guidance on these questions.

 

Best regards,

Colin
