APPLICATION INFORMATION
class-D effect on battery life
Battery operations for class-D amplifiers versus linear amplifiers have similar power supply savings results. The
essential contributing factor to longer battery life is lower RMS supply current. Figure 29 compares the
TPA005D14 supply current to the supply current of the TPA0202, a 2-W linear device, while playing music at
different peak voltage levels.

Figure 29. Supply Current vs Peak Output Voltage of TPA005D14 vs TPA0202 With Music Input
This plot shows that a linear amplifier has approximately three times more current draw at normal listening levels
than a class-D amplifier. Thus, a class-D amplifier has approximately three times longer battery life at normal
listening levels. If there is other circuitry in the system drawing supply current, that must also be taken into
account when estimating battery life savings.
