Notes on the electrical schematic shown in Figure 3 and 4
3.4.1
Main characteristics
●
2 channels single-ended or 1 channel bridge PWM amplifier
●
Power output: see Table 5
●
Figure 3: PLL option
●
Figure 4: free running oscillator option
●
Output voltage @ input = -6Bfs:
–
Figure 3: 10Vrms (single ended) - 20Vrms (bridge)
–
Figure 4: 9.5Vrms (single ended) - 19Vrms (bridge)
●
Clip detector settled at THD=10%
●
No dithering selected
The schematic is depicted showing the suggested structure of the printed circuit board
tracks (star points, high current path, components placement).
To avoid malfunctioning due to the parasitic inductance, short connections lengths are
recommended.
