ESD SENSITIVITY

The AD2S80A features an input protection circuit consisting of large “distributed” diodes and

polysilicon series resistors to dissipate both high energy discharges (Human Body Model) and

fast, low energy pulses (Charges Device Model).

The AD2S80A is ESD protection Class II (2000 V min). Proper ESD precautions are strongly

recommended to avoid functional damage or performance degradation. For further information

on ESD precautions, refer to Analog Devices ESD Prevention Manual.
