Chip Biasing options
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 ( Vds: internal Drain to Source voltage ).
N°2 : Do not bias in such a way that Vgs* becomes positive. (Vgs :internal Gate to Source voltage )
