INTERFACE TIMING
(Test Circuit of Figure 1, Figure 2, V+ = 5V, V- = -5V, DGND = AGND = 0V, T
Note 1: ±18-bit accuracy achieved by averaging multiple conversions.
Note 2: Maximum deviation from best straight-line fit.
Note 3: Guaranteed by design, not tested.
Note 4: Difference in reading for equal positive and negative inputs near full scale.
