2
Performance characterized with AD8676BRZ voltage reference buffers and 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
Valid for all voltage reference spans.
5
Guaranteed by design and characterization, not production tested.
6
The AD5781 is configured in the bias compensation mode with a low-pass RC filter on the output. R = 300 , C = 143 pF (total capacitance seen by the output buffer,
lead capacitance, and so forth).
7
Includes noise contribution from AD8676BRZ voltage reference buffers.
8
Current flowing in an individual logic pin.
9
Includes PSRR of AD8676BRZ voltage reference buffers.
