NOTES
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).
2tV and tPD are measured from the transition points of the ENCODE input to the 50%/50% levels of the digital outputs swing. The digital output load during test is
not to exceed an ac load of 10 pF or a dc current of ± 40 µA. Rise and fall times 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.
Specifications subject to change without notice.
