AD2S81A/AD2S82A–SPECIFICATIONS
ESD SENSITIVITY
The AD2S81A and AD2S82A features an input protection circuit consisting of large “distributed”
diodes and polysilicon series resistors to dissipate both high energy discharge (Human Body Model)
and fast, low energy pulses (Charges Device Model).
T
he AD2S81A and AD2S82A is ESD protection Class II (2000 V min). Proper ESD precautions are
strongly recommended to avoid functional damage or performance degradation. For further informa-
tion on ESD precautions, refer to Analog Devices ESD Prevention Manual.
