TPA6112A2DGQ Frequently Asked Questions (FAQs)

  • A good thermal layout is crucial for the TPA6112A2DGQ. TI recommends a 2-layer or 4-layer PCB with a solid ground plane on the bottom layer, and a thermal relief pattern on the top layer to dissipate heat efficiently.
  • The gain setting depends on the input signal level and the desired output power. TI provides a gain calculation formula in the datasheet. Typically, a gain of 20 dB is suitable for most audio applications, but you may need to adjust it based on your specific requirements.
  • The maximum recommended power supply voltage is 15 V, but the device can tolerate up to 16.5 V for short periods. Exceeding 16.5 V may cause damage to the device.
  • Use a combination of capacitors, inductors, and resistors to filter out noise and EMI. TI recommends a pi-filter (C-L-C) or a T-filter (L-C-R) configuration to reduce electromagnetic interference.
  • A 2nd-order Butterworth filter or a 3rd-order Chebyshev filter is recommended to filter out high-frequency noise and ensure a flat frequency response.
