Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general audio PCB layout best practices, such as separating analog and digital grounds, using a star-ground configuration, and minimizing trace lengths and loops.
To ensure stability, follow the recommended component values and PCB layout, and make sure to decouple the power supply with capacitors. Additionally, use a low-ESR capacitor for the output filter and avoid using long wires or traces for the output stage.
The maximum power dissipation of the LM49101TMX/NOPB is dependent on the ambient temperature and the thermal resistance of the package. According to the datasheet, the maximum power dissipation is 2.5W at 25°C ambient temperature. However, it's recommended to derate the power dissipation based on the actual operating conditions.
Yes, the LM49101TMX/NOPB is a mono amplifier, but it can be used in a stereo application by using two devices, one for each channel. Make sure to follow the recommended PCB layout and component values for each channel.
The recommended input impedance for the LM49101TMX/NOPB is between 1kΩ and 10kΩ. This ensures that the input stage is properly biased and that the amplifier operates within its specified parameters.
