Performance characterized with the AD8675ARZ output buffer.
3
Linearity error refers to both INL error and DNL error, either parameter can be expected to drift by the amount specified after the length of time specified.
4
The AD5780 is configured in the unity-gain mode with a low-pass RC filter on the output. R = 300 Ω, C = 143 pF (total capacitance seen by the output buffer, lead
capacitance, and so forth).
