and After Calibration for VDC

in
Note: The absolute error data shown in the graphs above reflects the effects of both gain error and offset
error. The data was taken on 25 parts: five each from four processing corner lots as well as five from one
nominally processed lot, each at three temperatures: -40°C, 27°C, and 150°C (giving the 75 data points
shown above), for two input DC voltages: 0.60V and 2.70V. The data indicates that for the given
population of parts, calibration significantly reduced (by as much as 24%) the collective variation (spread)
of the absolute error of the population. It also significantly reduced (by as much as 38%) the mean
(average) of the absolute error and thereby brought it significantly closer to the ideal value of zero.
Although not guaranteed, it is believed that calibration will produce results similar to those shown above
for any population of parts including those which represent processing and temperature extremes.

illustrates the ADC input circuit during sample and hold. S1 and S2 are always open/closed
at the same time that S3 is closed/open. When S1/S2 are closed & S3 is open, one input of the sample and
