Precision DACs: DC Specifications

In this video, we learn about the basic DC specifications of Precision DACs. We begin by introducing the ideal DAC transfer function. Then we learn about the errors that cause a DAC to deviate from ideal:

• Offset and zero-code error
• Gain error
• Differential non-linearity (DNL)
• Integral non-linearity (INL)

We then finish by discussing total unadjusted error (TUE) which is an effective way of summarizing the DC errors of a DAC.
