PROCEDURE FOR AMPLIFIER OPERATION AND TEST
1) Slug must be thermally and electrically connected to obtain rated performance
2) The V
SS
Voltage should be applied first to the amplifier prior to V

may be used as monitor points to verify that the bias circuit is working properly. These
pins should measure as negative voltage potential, after V
SS
is applied.
4) The Bias Pins V

and V
REF
may be applied with no V
SS
voltage present
5) Always Follow ESD precautions when handling these devices
