Other Parts Discussed in Thread: DAC7718
Hi all,
Although I am debugging the substrate in which DAC7718 was carried,
Things occurs as follows.
(1) It is since "RESET SEL" and "USB/BTC" are set to IOVdd,
At least 8V is outputted although it seems that Vout is set to 0V at the time of POWER-ON RESET.
(2) Output voltage is not in agreement with the code of transmission data, and it becomes the following touch.
(It is used by Twos Complement Code of Bipoler Output.)
Data=800h→ -14.52V
Data=900h→ -12.143V
Data=A00h→ -9.743V
Data=000h→ 8.557V
Data=001h→ 1.557V
Data=002h→ 1.057V
It is about Register Map.
Configuration Register has set up by "100000000000000".
Offset DAC-A DATA has set up 19Ah.
Offset DAC-B DATA has set up 19Ah.
About this, Isn't there any reply?
Best Regerds,
Hisa Kobayashi.
