Part Number: ADS7843

Hi support team.

I have some question from my customer below.

- Are settings immediately after startup of PD0 / PD1 "00" or "11"?

I would like to know the initial settings of PDx.

- Is there a limit to the VCC startup time?

- The maximum frequency of DCLK is 2.5MHz, is it correct?

I appreciate if you give me some info to me.

Best regards,

Higa

Hello Higa,

I have not encountered this part before on this forum, give me 24 hours to do research on settings for initialization for you and I will reply with desired specifications.

Best Regards,

Hello,

Sorry for that delay.

The default I believe would be "00" for PD0/PD1

There is no specification I can give on Vcc start-up time unfortunately.

Yes DCLK is at max at 2.5MHz

Best,

Carson
