Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(1)
The relative accuracy or integral nonlinearity (INL), sometimes referred to as linearity error, is the maximum deviation of the output from
the line between zero and full scale excluding the effects of zero code and full-scale errors (see text). Tested from code 3 to code 1024.
(2)
The differential nonlinearity (DNL), sometimes referred to as differential error, is the difference between the measured and ideal 1LSB
amplitude change of any two adjacent codes. Monotonic means the output voltage changes in the same direction (or remains constant)
as a change in the digital input code. Tested from code 3 to code 1024.
(3)
Zero-scale error is the deviation from zero-voltage output when the digital input code is zero (see text).
(4)
Zero-scale-error temperature coefficient is given by: EZS TC = [EZS (Tmax) – EZS (Tmin)]/Vref × 106/(Tmax– Tmin).
(5)
Gain error is the deviation from the ideal output (Vref – 1LSB) with an output load of 10k excluding the effects of the zero-scale error.
(6)
Gain temperature coefficient is given by: EG TC = [EG(Tmax) – EG (Tmin)]/Vref × 106/(Tmax– Tmin).
(7)
Zero-scale-error rejection ratio (EZS-RR) is measured by varying the VDD from 4.5V to 5.5V dc and measuring the proportion of this
signal imposed on the zero-code output voltage.
(8)
Gain-error rejection ratio (EG-RR) is measured by varying the VDD from 4.5V to 5.5V dc and measuring the proportion of this signal
imposed on the full-scale output voltage after subtracting the zero-scale change.
