2.2 W BTL audio amplifier
The characteristics curves (
Figure 11
a and
Figure 11
b,
Figure 12
,
Figure 13
a and
Figure 13
b, and
Figure 14
) show the room temperature performance for SA58632 using
the demo PCB shown in
Figure 23
. For example,
Figure 11 “Power dissipation versus
output power”
(a and b) show the performance as a function of load resistance and supply
voltage. Worst case power dissipation is shown in
Figure 12
.
Figure 13
a shows that the
part delivers typically 2.8 W per channel for THD+N = 10 % using 8
load at 9 V supply,
while
Figure 13
b shows that the part delivers 3.3 W per channel at 12 V supply and 16
load, THD+N = 10 %.
