Printed Circuit Board Layout
Figure 5 and Figure 6 show printed circuit board layouts for
the LM1896 and LM2896. The circuits are wired as stereo
amplifiers. The signal source ground should return to the
input ground shown on the boards. Returning the loads to
power supply ground through a separate wire will keep the
THD at its lowest value. The inputs should be terminated in
less than 50 k
X
to prevent an input-output oscillation. This
oscillation is dependent on the gain and the proximity of the
bridge elements R
B
and C
B
to the (
a
) input. If the bridge
mode is not used, do not insert R
B
, C
B
into the PCB.
To wire the amplifer into the bridge configuration, short the
capacitor on pin 7 (pin 1 of the LM1896) to ground. Connect
together the nodes labeled BRIDGE and drive the capacitor
connected to pin 5 (pin 14 of the LM1896).
