Application Information (Continued)
RECOMMENDED PRINTED CIRCUIT BOARD LAYOUT
Figure 5 through Figure 7 show the recommended two-layer
PC board layout that is optimized for the TO263-packaged
LM4940 and associated external components. This circuit
board is designed for use with an external 12V supply and
4
Ω(min) speakers.
This circuit board is easy to use. Apply 12V and ground to
the board’s V
DD and GND pads, respectively. Connect a
speaker between the board’s OUT
A and OUTB outputs and
their respective GND terminals.
