Preliminary
Figure 10-22 ADC Absolute Error Over Processing and Temperature Extremes
Before and After Calibration for VDCin = 0.60V and 2.70V
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 15 parts: three each from four processing corner lots as well as
three from one nominally processed lot, each at three temperatures: -40°C, 27°C, and 150°C
(giving the 45 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
1.
INL measured from Vin = .1VREFH to Vin = .9VREFH
10% to 90% Input Signal Range
2.
LSB = Least Significant Bit
3.
ADC clock cycles
4.
Assumes each voltage reference pin is bypassed with 0.1
F ceramic capacitors to ground
5.
The current that can be injected or sourced from an unselected ADC signal input without impacting the performance of
the ADC. This allows the ADC to operate in noisy industrial environments where inductive flyback is possible.
6.
Absolute error includes the effects of both gain error and offset error.
