Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general high-current PCB design guidelines, such as using thick copper traces, minimizing inductance, and providing adequate heat sinking.
The output filter design depends on the specific application requirements, but a general rule of thumb is to use a 2nd-order LC filter with a cutoff frequency around 100 kHz to 200 kHz. TI also provides a filter design tool to help with this process.
The maximum ambient temperature for the TAS5612APHD is 85°C, but it's recommended to derate the device's power dissipation at higher temperatures to ensure reliable operation.
The TAS5612APHD has built-in overcurrent protection, but it's still important to add external protection circuitry, such as fuses or current-sensing resistors, to prevent damage from overvoltage or overcurrent conditions.
The recommended input capacitor value depends on the specific application requirements, but a general rule of thumb is to use a capacitor with a value of at least 10 μF to 22 μF to ensure stable operation.
