1/ TA = +25 °C, TA Max = +125 °C, TA Min = -55 °C. VDD = 3.0V, VD = 3.0V; single-ended input; external reference, unless otherwise noted.
2/ Gain error and gain temperature coefficient are based on the ADC only (with a fixed 1.25V external reference).
3/ tPD is measured from the 1.5V level 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.
4/ Power dissipation measured with encode at rated speed and a dc analog input.
5/ SNR/harmonics based on an analog input voltage of -0.7 dBFS referenced to a 1.024 V full-scale input range.
