Dear, All
Customer has questions about ADS78xx.
I got a schematic schematic around the ADS7807 from customers.
With this circuit configuration, Vana and Vdig are stable and data of ADC is read after 100 mS or more.
At this time the voltage of R1in was 0.6V.
When this phenomenon occurred, this value was 0x3FFB only for the first access.
The Read value from the ADC should be around 0x8881 if it is normal.
Can you find the cause of this phenomenon occurrence?
Thanks, Masami M.
