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: θ JC = 46 °C/W, θ CA = 80 °C/W, θ JA = 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.

Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD9283 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.

This is a stress rating only; functional operation of the device at these or any other conditions outside of those indicated in the operation sections of this specification is not implied. Exposure to absolute maximum ratings for extended periods may affect device reliability. WARNING! ESD SENSITIVE DEVICE |
