External Components and Application Schematics
Figure 6-2 is a simplified schematic for the external class-D predriver.
Input resistor (RPR or RPL) sets the gain of the external class D. For TPS2010D1, the gain is defined according to the
following equation:
Gain (V/V) = 2*150*103/(RPR or RPL)
RPR or RPL > 15 k
