Note 1: Integral nonlinearity is the derivation of the analog values at any code from its theoretical value after nulling the gain error
and offset error.
Note 2: Offset calibrated.
Note 3: Offset nulled.
Note 4: The input voltage range for the analog inputs is given with respect to the voltage on the negative input of the differential pair.
Note 5: For the range of V AIN+ or V AIN- = -2.2V to +2.2V and V REF+ or V REF- = -2.2V to +2.2V.
Note 6: External load must be constant during conversion for specified accuracy. Guaranteed specification of 2mV/mA is a result of
production test limitations.
Note 7: Measured at DC by changing the power-supply voltage from 2.7V to 5.25V and measuring its effect on the conversion error.
PSRR at 50Hz and 60Hz exceeds 120dB with filter notches of 10, 20, 30, 40, 50, or 60Hz.
Note 8: Analog power-supply currents are measured with all digital inputs at either GND or DV DD . Digital power-supply currents
measured with all digital inputs at either GND or DV DD .
