TPA3116D2QDADRQ1 Frequently Asked Questions (FAQs)

  • According to TI's application note, a 10uF ceramic capacitor and a 1uF ceramic capacitor in parallel, placed close to the power pins, are recommended for power supply decoupling.
  • TI recommends a 4-layer PCB with a solid ground plane, and to keep the audio signal traces away from the power supply traces. Additionally, use a star-grounding configuration and avoid routing audio signals under the IC.
  • The maximum power dissipation of the TPA3116D2 is 15W, assuming a 50°C ambient temperature and a 4-layer PCB with a solid ground plane.
  • Yes, the TPA3116D2 can be used in a bridged configuration, but it requires an external amplifier to drive the other half of the bridge. TI provides an application note (SLAA461) that details the design considerations for a bridged configuration.
  • TI recommends using a voltage supervisor (e.g., TLV703) to monitor the power supply voltage and reset the TPA3116D2 if it falls outside the recommended operating range (10V to 26V).
