Internal DC schematic

This chip is self-biased, and flexibility is provided by the access to positive Vg.

The internal DC electrical schematic is given in order to use these pads in a safe way.

Absolute recommandations:

N°1 : Do not exceed Vds* = 3,5 Volt ( internal Drain to Source voltage ).

N°2 : Do not bias in such a way that Vgs* becomes positive. (:internal Gate to Source

voltage )
