PROCEDURE FOR AMPLIFIER OPERATION AND TEST 1) Slug must be thermally and electrically connected to obtain rated performance 2) The VSS Voltage should be applied first to the amplifier prior to VD1, VD2, VD3, or VD4 voltages 3) VGS1, VGS2, VGS3, VGS4 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 VDD and VREF may be applied with no VSS voltage present 5) Always Follow ESD precautions when handling these devices
