NOTES
1Stop band repeats itself at multiples of 64 × fS, where fS is the output word rate. Thus the digital filter will attenuate to 0 dB across the frequency spectrum except
for a range ± 0.55 × 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 AD1870 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!
