Integral nonlinearity is the deviation of the analog value at any code from its theoretical value after nulling the gain error
and offset error.
Offset calibrated. See OFFSET_CAL1 AND OFFSET_CAL2 in the On-Chips Registers section.
Offset nulled.
Offset-drift error is eliminated by recalibration at the new temperature.
The input voltage range for the analog inputs is given with respect to the voltage on the negative input of the differential pair.
V
AIN+ and REF+ only. V
Measured at DC by changing the power-supply voltage from 2.7V to 5.25V and measuring the effect on the conversion
error with external reference. PSRR at 50Hz and 60Hz exceeds 120dB with filter notches at 50Hz and 60Hz
CLK and SCLK are disabled.
