Figure 9. Typical Stereo Full Bridge Configuration to Obtain 50+50W @ THD = 10%, RL = 8Ω, VCC =29V

Figure 10. Typical Single BTL Configuration to Obtain 70W @ THD 10%, RL = 8Ω, VCC = 34V (note 1))

Note: 1. "A PWM modulator as driver is needed . In particular, this result is performed using the STA308+STA518A+STA50X demo board".
