The digital output load during test is not to exceed an ac load of 10 pF or a dc current of ± 40 µA. 3SNR/harmonics based on an analog input voltage of –0.5 dBFS referenced to a 1.0 V full-scale input range. 4Digital supply current based on VDD = 3 V output drive with <10 pF loading under dynamic test conditions. 5Power dissipation is based on 60 MSPS encode and 10.3 MHz analog input dynamic test conditions (VD = 5 V ± 5%, VDD = 3 V ± 5%). 6Typical thermal impedance for the RS style (SSOP) 28-lead package: θJC = 39°C/W, θCA = 70°C/W, and θJA = 109°C/W. Specifications subject to change without notice.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD9059 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. REV.
