Gain Error  
Definitions of Specifications  
The first code transition should occur at an analog value 1/2 LSB  
above negative full scale. The last transition should occur at an analog  
value 1 1/2 LSB below the nominal full scale.  
Integral Nonlinearity (INL)  
INL refers to the deviation of each individual code from a line drawn  
from “negative full scale” through “positive full scale.” The point used  
as “negative full scale” occurs 1/2 LSB before the first code transition.  
“Positive full scale” is defined as a level 1 1/2 LSB beyond the last  
code transition. The deviation is measured from the middle of each  
particular code to the true straight line.  
Gain error is the deviation of the actual difference between first and  
last code transitions and the ideal difference between first and last  
code transitions.  
Temperature Drift  
The temperature drift for zero error and gain error specifies the maximum  
change from the initial (+25°C) value to the value at -55°C or +125°C.  
Differential Nonlinearity (DNL, No Missing Codes)  
An ideal ADC exhibits code transitions that are exactly 1 LSB apart.  
DNL is the deviation from this ideal value. Guaranteed no missing  
codes to 12-bit resolution indicate that all 4096 codes, respectively,  
must be present over all operating ranges.  
Aperture Jitter  
Aperture jitter is the variation in aperture delay for successive samples  
and is manifested as noise on the input to the A/D.  
Aperture Delay  
Zero Error  
Aperture delay is a measure of the sample-and-hold amplifier (SHA)  
performance and is measured from the rising edge of the clock input  
to when the input signal is held for conversion.  
The major carry transition should occur for an analog value 1/2 LSB  
below VINA = VINB. Zero error is defined as the deviation of the  
actual transition from that point.
