NOTES
1
Gain error and gain temperature coefficients are based on the ADC only (with a fixed 2.5 V external reference and a 2 V p-p differential analog input).
2
t
V
and t
PD
are measured from the transition points 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
μ
A. Rise and fall times measured from 10% to 90%.
3
Power dissipation measured with encode at rated speed and a dc analog input. (Outputs Static, I
VDD
= 0.)
4
SNR/harmonics based on an analog input voltage of –0.5 dBFS referenced to a 2 V full-scale input range.

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 AD9432 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.
WARNING!
ESD SENSITIVE DEVICE
*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.
