8.2.2.4 DAC

After sufficient bypass, this precision reference voltage is applied to the VREF pin of the DAC8830 device. An accurate reference along with an accurate DAC are largely responsible for the overall accuracy of the current loop, as any accuracy errors associated with the DAC will propagate through the rest of the signal chain and decrease the accuracy of the solution. In this case, the DAC8830, a 16-bit voltage-output DAC with excellent linearity (1 LSB INL), low glitch, low noise, and fast settling was chosen to set the base line performance of the design.
