We are Planning to use ADS7945 in our design.
In Evaluation Board we observed one D-Flip Flop to drive the Input.
Is that necessary to drive? or can we connect…
Hi Collin,
I an sorry that I cannot understand fully of your saying.
the result is that i should find another IC instead of ADS7945?
then what is the suitable IC for our purpose? would you recommend for me?
Best regards,

Part Number: ADS7945 Hi team,
Looking at the DEVICE OPERATION of 16-clock mode in the datasheet, SDO is kept LOW durind 15 and 16 cycle of SCLK. However, customer found that SDO is pulled HIGH at 16 cycle of SCLK. Is this a correct behavior?
SDO was…
Part Number: ADS7945 Hi support team,
I have a question regarding PCB layout of ADS7945 . It is recommended in the datasheet of ADS7945 that a spilt ground plane for analog and digital enables better results.
And the ADS7945 ground pins are connected to…
