REV. D
Gain error and gain temperature coefficient are based on the ADC only (with a fixed 2.5 V external reference).
t
SNR/harmonics based on an analog input voltage of –0.5 dBFS referenced to a 1.0 V full-scale input range.
Digital supply current based on V
Power dissipation is based on specified encode and 10.3 MHz analog input dynamic test conditions (V
