(1)All typical values are at TA = +25
°
C.
(2)Integral nonlinearity is defined as the maximum deviation of the line through the end points of the specified input range of the transfer curve
for VIN+ = 250mV to +250mV, expressed either as the number of LSBs or as a percent of measured input range (500mV).
(3)Ensured by design.
(4)Maximum values, including temperature drift, are ensured over the full specified temperature range.
(5)With reduced accuracy, minimum clock can go from 1MHz up to 32MHz.
