I have a question from our customer about OTI function of AD7418.He wants to use A1 input for this OTI function.But it seems that the OTI only be function for channel 0 from data sheet.
In table-6 "AD7418 Pin Function Descriptions" , indicated as followings.
OTI : This is a logic output. The OTI is set if the result of a conversion on Channel 0 (temperature sensor) is greater than an 8-bit word in the TOTI setpoint register. The signal is reset at the end of a serial read operation.
" OTI only be function for channel 0. "
Is this recognition correct ?
Thank you for your support.
> I understand they want to use an external temp sensor rather than the onboard sensor?
Yes, the customer wants to use external temp sensor.
I think that I introduce ADT7411 to the customer.
It wiil need to change the thresihold by every INT event to make hysterisys.
