The digital output load during test is not to exceed an ac load of 10 pF or a dc current of ± 40 µA. 3Power dissipation measured with encode at rated speed and a dc analog input. 4Typical thermal impedance for the RS style (SSOP) 20-lead package: θJC = 46°C/W, θCA = 80°C/W, θJA = 126°C/W. 5SNR/harmonics based on an analog input voltage of –0.7 dBFS referenced to a 1.024 V full-scale input range.
