CLASS-D OPERATION
TRADITIONAL CLASS-D MODULATION SCHEME
SLOS418D – SEPTEMBER 2003 – REVISED MARCH 2008
Figure 13. Typical Application Circuit
This section focuses on the class-D operation of the TPA3007D1.
The traditional class-D modulation scheme, which is used in the TPA032D0x family, has a differential output
where each output is 180 degrees out of phase and changes from ground to the supply voltage, VCC. Therefore,
the differential pre-filtered output varies between positive and negative VCC, where filtered 50% duty cycle yields
0 V across the load. The traditional class-D modulation scheme with voltage and current waveforms is shown in
Figure 14. Note that even at an average of 0 V across the load (50% duty cycle), the current to the load is high,
causing high loss, thus causing a high supply current.
