× 2.2 W BTL audio amplier
the demo PCB shown in Figure 16. For example, Figure 12 “Power dissipation as a
function of 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 13. Figure 15a
shows that the part delivers typically 2.8 W per channel for THD+N = 10 % using 8
load
at 9 V supply, while Figure 15b shows that the part delivers 3.3 W per channel at 12 V
supply and 16
load, THD+N = 10 %.
