Electrical Characteristics for Bridged Mode Operation (Notes 7, 10) (Continued)
Note 16: All bumps have the same thermal resistance and contribute equally when used to lower thermal resistance. The LM4838ITL demo board (views featured
in the Application Information section) is a four layer board with two inner layers. The second inner layer is a VDD plane with the bottom outside layer a GND plane.
The planes measure 1,900mils x 1,750mils (48.26mm x 44.45mm) and aid in spreading heat due to power dissipation within the IC.
Note 17: All bumps have the same thermal resistance and contribute equally when used to lower thermal resistance. The LM4838GR Demo Board is a four layer
PC Board with 2 inner layers. The second inner layer and bottom outside layers are both grounded. The planes measure 3200 x 3700 mills and aid in spreading
heat due to power dissipation within the IC.

Note 18: If system beep is detected on the Beep In pin, the system beep will be passed through the bridged amplifier regardless of the logic of the Mute and HP
sense pins.
