2 Performance characterized with AD8676BRZ voltage reference buffers and AD8675ARZ output buffer.
3 Guaranteed by design and characterization, not production tested.
4 Valid for all voltage reference spans.
5 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.
6 AD5791 configured in X2 gain mode, 25 pF compensation capacitor on AD797.
7 Includes noise contribution from AD8676BRZ voltage reference buffers.
8 The AD5791 is configured in bias compensation 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).
9 Current flowing in an individual logic pin.
10 Includes PSRR of AD8676BRZ voltage reference buffers.
