a. VCC = 9 V; RL = 16 Ω; f = 1 kHz.
b. VCC = 11 V; RL = 25 Ω; f = 1 kHz.
(1) Measured on the standard printed-circuit board without an additional heatsink (see Figure 14). These curves Influence of
thermal feedback caused by the high power dissipation in combination with the high thermal resistance of the plastic
package.
(2) Measured with a small heatsink on top of the plastic package body; Rth(h-a) = 30 K/W.
