TPA3004D2PHPR datasheet by Texas Instruments

TPA3004D2PHPR Frequently Asked Questions (FAQs)

• What is the recommended power supply decoupling for the TPA3004D2PHPR?
  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.
• How do I optimize the PCB layout for the TPA3004D2PHPR?
  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. Also, avoid routing signals under the amplifier.
• What is the maximum power dissipation of the TPA3004D2PHPR?
  The maximum power dissipation of the TPA3004D2PHPR is 15W. However, this value can be affected by the ambient temperature, PCB design, and heat sinking. Ensure proper thermal management to prevent overheating.
• Can I use the TPA3004D2PHPR in a bridged configuration?
  Yes, the TPA3004D2PHPR can be used in a bridged configuration to increase the output power. However, this requires careful consideration of the power supply, speaker impedance, and thermal management to avoid overheating and ensure reliable operation.
• How do I protect the TPA3004D2PHPR from overvoltage and undervoltage conditions?
  Use a voltage regulator or a voltage supervisor to ensure the power supply voltage remains within the recommended range (8V to 26V). Additionally, consider adding overvoltage protection (OVP) and undervoltage protection (UVP) circuits to prevent damage from voltage transients.
