Fig 10. Power dissipation versus ambient temperature
The characteristics curves (Figure 11a and Figure 11b, Figure 12, Figure 13a and
Figure 13b, 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 13a shows that the
part delivers typically 2.8 W per channel for THD+N = 10 % using 8 Ω load at 9 V supply,
while Figure 13b shows that the part delivers 3.3 W per channel at 12 V supply and 16 Ω
load, THD+N = 10 %.
