Notes:

Integral Linearity, for the SP9502, 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.

Differential Linearity is the deviation of an output step from the theoretical value of 1 LSB for any two

adjacent digital input codes.

1 LSB = 2*V

REF/4,096.

REF = 0V.

The following power up sequence is recommended to avoid latch up: VSS (-5V), VDD (+5V), REFIN.
