The digital output load during testing is not to exceed an ac load of 10 pF or a dc current of ±40 μA. Rise and fall times are measured from 10% to 90%. 3 Power dissipation measured with encode at rated speed and a dc analog input (outputs static, IVDD = 0). 4 SNR/harmonics based on an analog input voltage of –0.5 dBFS referenced to a 2 V full-scale input range.
