NOTE
1Stopband repeats itself at multiples of 64 × FS, where FS is the output word rate. Thus the digital filter will attenuate to 115 dB across the frequency spectrum
except for a range ± 0.5458 × FS wide at multiples of 64 × FS.
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 AD1878/AD1879 features proprietary ESD protection circuitry, permanent dam-
age 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!
