Texas Instruments provides a recommended PCB layout in the datasheet, which includes a suggested component placement and routing guide to minimize electromagnetic interference (EMI) and ensure optimal performance.
The gain setting depends on the input signal level and the desired output power. The TPA2028D1YZFR has a gain range of 20 dB to 30 dB. A higher gain setting can provide more output power, but may also increase noise and distortion. A lower gain setting can provide a cleaner signal, but may not provide enough output power.
The maximum power dissipation of the TPA2028D1YZFR is 2.5 W. This is specified in the datasheet and is dependent on the ambient temperature and the thermal resistance of the package.
To protect the TPA2028D1YZFR from overheating, ensure good thermal conductivity between the device and the PCB, use a heat sink if necessary, and avoid operating the device at high ambient temperatures or with high power dissipation.
The recommended input capacitor value is 2.2 μF to 4.7 μF, depending on the input signal frequency and impedance. A larger capacitor value can provide better noise filtering, but may also increase the risk of oscillation.
