Mike,
If you reference page 7 & 8 you will see that REFn is the voltage reference input. And as you guessed RFBn is a resistor implementing in the same technology as the ladder resistors and as such can be expected to be of the similar accuracy and exhibit a similar temperature gradiant as the ladder resistors which makes it very useful to the external I-convertor as a feedback resistor. regards, p |
