DEARS.
Customer uses DAC8531.
It is not working properly in a low temperature test.
Setting DAC at low temperature is output 0V.
It is an abnormal operation.
The low temperature test temperature is -30 degrees.
SPI operates normally at low temperature(-30 degrees).
We are testing the chamber.
Raising the temperature will normally work.
What is the solution?
I would like a guide.
It is a circuit diagram of a customer.
Thank you
