Notes:
1.
Integral Linearity, for the SP9500, is measured as the arithmetic mean value of the magnitudes of the
greatest positive deviation and the greatest negative deviation from the theoretical value for any given
input condition.
2.
Differential Linearity is the deviation of an output step from the theoretical value of 1 LSB for any two
adjacent digital input codes.
3.
1 LSB = (V
REF-AGND)/4,096.
4.
V
REF = AGND = 2.5V.
5.
The following Power up sequence is recommended: VDD (+5V), VREF.
