I am considering DAC circuit that circuit is using DAC8820IC and OP277UA and REF5010I based on figure 42 on DAC8820 data sheet.
Also I am anlysing output voltage error for this circuit.
I would like to inquire output voltage error culculate method for this circuit.
I think that I will use below equation for calculating output voltage error.
If below equiation has missunderstanding, please tell me.
< Equation >
Output voltage (include error) = VREF(10V +/-0.05%) X (Digital code/32768 -1) + DAC output voltage error + OP277(I/V convert) input offset voltage (+/-100uV)
* DAC output voltage error: Bipolar zero scale error (+/-8LSB max) + Full-scale gain error (+/-16LSB max) + Relative accuracy (+/-1LSB max) + DNL (+/-1LSB max)
