I´m using the DAC 121C085 VSSOP 5V at Vref I write full-scale (FFFh) I have in the output 4.263V
If I writ (BFFh) I have 3.6V and I have 1.6V when I write (800h)
The VA pin is left float.
I'm sure the code is correct because when read back e reading value is correct.
I am forgetting something ?
Thanks for the help!
Mike
