¹Gain error and gain temperature coefficients are based on the ADC only (with a fixed 2.5 V external reference and a 2 V p-p differential analog input).

²t_Vand t_PDare measured from the transition points of the ENCODE input to the 50%/50% levels of the digital output swing. 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%.

³Power dissipation measured with encode at rated speed and a dc analog input (outputs static, I_VDD= 0).

⁴SNR/harmonics based on an analog input voltage of –0.5 dBFS referenced to a 2 V full-scale input range.
