Texas Instruments recommends using a 10uF capacitor in parallel with a 100nF capacitor, both connected between the power supply pins (VCC and GND) to ensure stable operation.
To minimize electromagnetic interference (EMI) and ensure optimal performance, keep the power supply traces short and wide, use a solid ground plane, and place the amplifier close to the speaker. Additionally, use a common ground point for the amplifier and the speaker.
The maximum power dissipation of the TPA3002D2PHPR is 15W. However, this value can be affected by the ambient temperature, PCB design, and other factors. It's essential to ensure proper heat sinking and thermal management to prevent overheating.
Yes, the TPA3002D2PHPR can be used in a bridged configuration to increase the output power. However, this requires careful consideration of the power supply, PCB layout, and thermal management to ensure reliable operation.
To protect the amplifier from overvoltage and undervoltage conditions, use a voltage regulator or a voltage supervisor to ensure the power supply voltage remains within the recommended operating range (8V to 26V). Additionally, consider using overvoltage protection (OVP) and undervoltage protection (UVP) circuits.
