Texas Instruments provides a recommended PCB layout in the TPA6130A2 datasheet, which includes guidelines for component placement, trace routing, and thermal management. Additionally, the TI website has a PCB layout guide that provides more detailed information.
The gain setting of the TPA6130A2 depends on the input signal level and the desired output power. The datasheet provides a gain setting table that can be used as a starting point. Additionally, TI's Audio Amplifier Quick Start Guide provides a gain calculation formula and examples to help with gain selection.
The maximum power dissipation of the TPA6130A2 is dependent on the ambient temperature and the thermal resistance of the PCB. The datasheet provides a power dissipation calculation formula and a thermal resistance table to help estimate the maximum power dissipation. Typically, the maximum power dissipation is around 2.5W.
To reduce EMI and noise, it is recommended to use a solid ground plane, keep the input and output traces short and away from each other, and use a common-mode filter on the input. Additionally, the datasheet provides guidelines for component selection and placement to minimize EMI and noise.
The recommended input capacitor value for the TPA6130A2 is dependent on the input signal frequency and amplitude. A general rule of thumb is to use a capacitor with a value of 1uF to 10uF, with a voltage rating of at least 2x the input signal amplitude. The datasheet provides more detailed information on input capacitor selection.
