Part Number: ADS8681

Hello Dale,

i have one more query.

in ads8681 i did the daisy chain connections for two devices exactly as follows

.

so while configuring the device .. SDO of the processor transmit the data to the SDI of the 1st device..then what about the 2nd device? because the SDI of 2nd device is connected to the SDO of the 1st.

???

    Hi Kanchan,

    It looks like you posted the same query twice. Please review the ADS8681 datasheet, Figure 73 on page 39. All devices in the daisy chain should be configured the same way, you would need to send the 32-bit configuration data twice so that it was clocked into the second device in the chain.
