According to TI's application notes, a 10uF ceramic capacitor and a 1uF ceramic capacitor in parallel, placed close to the power pins, are recommended for power supply decoupling.
The gain setting depends on the input signal level and the desired output power. TI recommends using the gain equation provided in the datasheet to calculate the optimal gain setting for your specific application.
The maximum power dissipation of the TPA6112A2DGQR is 2.5W. However, this value can be affected by the ambient temperature, PCB layout, and other factors. TI recommends following the thermal design guidelines in the datasheet to ensure reliable operation.
Yes, the TPA6112A2DGQR can be used in a bridged configuration to increase the output power. However, TI recommends following the specific bridging configuration guidelines in the datasheet to ensure proper operation and to avoid damage to the device.
TI recommends following the PCB layout guidelines in the datasheet, which include keeping the power supply traces short and wide, using a solid ground plane, and placing the input and output capacitors close to the device.
