Hello, I am testing DA8718.
I got a problem that DAC outputs offset voltage(about 8V) .
When I supply each +5V and+-12V at the different time, separately, the DAC outputs right voltage in +-10V range (reference voltage 3V).
But When I suppl volage +5V and +-12V to DAC at the same time, DAC outputs wrong voltage.
Then, I supplied the voltage as following steps.
1) I disconnect the +5V line. And remain +-12V at the same time.
2) I reconnect the +5V line.
In this case, the DAC outputs right voltage well.
I read the datasheet page 44. I did pull up the LDAC, RST, CLEAR, etc.
What do I initialize for DAC8718?
Thanks for reading.
