Application Information EXPOSED-DAP PACKAGE PCB MOUNTING CONSIDERATIONS The LM4835’s exposed-DAP (die attach paddle) packages (MTE and LQ) provide a low thermal resistance between the die and the PCB to which the part is mounted and soldered. This allows rapid heat ...
Page 16
Application Information However, a direct consequence of the increased power de- livered to the load by a bridge amplifier is higher internal power dissipation for the same conditions. The LM4835 has two operational amplifiers per channel. The maximum internal power ...
