RECOMMENDED PRINTED CIRCUIT BOARD LAYOUT
Figures 2 through 6 show the recommended four-layer PC board layout that is optimized for the 20-pin MH-packaged LM4869
and associated external components. This circuit is designed for use with an external 5V supply and 3
(or higher) speakers (or
load resistors).
This circuit board is easy to use. Apply 5V and ground to the board’s V
DD and GND terminals, respectively. Connect speakers (or
load resistors) between the board’s -OUTA and +OUTA and -OUTB and +OUTB pads. Apply balanced differential stereo input
signals to the input pins labeled ’-INA,’ ’+INA,’ ’-INB,’ and ’+INB.’
