According to TI's application notes, a 10uF ceramic capacitor in parallel with a 1uF ceramic capacitor is recommended for power supply decoupling to ensure stable operation and minimize noise.
The gain setting depends on the specific application requirements. TI recommends using the gain equation provided in the datasheet to calculate the required gain resistors. Additionally, consider the input impedance, output impedance, and desired signal-to-noise ratio when selecting the gain setting.
The maximum power dissipation of the TPA701DGN 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 essential to perform thermal calculations and consider heat sinking to ensure reliable operation.
Yes, the TPA701DGN can be used as a line driver. However, it's essential to consider the output impedance, load impedance, and cable capacitance to ensure signal integrity and minimize signal loss. TI recommends using a series resistor and capacitor network to match the output impedance to the load impedance.
To reduce EMI and RFI, TI recommends using proper PCB layout techniques, such as separating analog and digital grounds, using a solid ground plane, and minimizing loop areas. Additionally, consider using EMI filters, shielding, and ferrite beads to reduce radiated emissions.
