ESD-Protection

All pins have an ESD Protection of >2000V. Additionally the pins VDDE, VSSE and AOUT have an ESD

Protection of >4000V.

ESD Protection referred to the human body model is tested with devices in SSOP14 packages during product

qualification. The ESD test follows the human body model with 1.5kOhm/100pF based on MIL 883, Method

3015.7.
