NOTES
1Gain error and gain temperature coefficient are based on the ADC only (with a fixed 1.25 V external reference).
2tV and tPD are measured from the 1.5 V 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.
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.
Specifications subject to change without notice.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. 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.

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 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.
