TDA7498ETR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TDA7498ETR should ensure that the power supply lines are separated from the signal lines, and that the analog and digital grounds are separated. A 4-layer PCB with a dedicated power plane and a dedicated ground plane is recommended. The datasheet provides some guidelines, but a more detailed application note is available from STMicroelectronics.
  • To optimize thermal performance, ensure good airflow around the device, and use a heat sink if possible. The TDA7498ETR has a thermal pad on the bottom, so use a thermal interface material (TIM) to improve heat transfer. Keep the device away from other heat sources, and avoid blocking airflow around the device.
  • The recommended input capacitor value for the TDA7498ETR is 220nF to 470nF, depending on the input voltage and the desired ripple rejection. A larger capacitor value can provide better ripple rejection, but may increase the startup time.
  • The TDA7498ETR can be configured for mono or stereo operation by connecting the relevant pins. For mono operation, connect the LOUT and ROUT pins together, and connect the L_IN and R_IN pins together. For stereo operation, keep the LOUT and ROUT pins separate, and connect the L_IN and R_IN pins to separate input sources.
  • The maximum power output of the TDA7498ETR depends on the supply voltage and the load impedance. With a 24V supply voltage, the maximum power output is 50W per channel into a 4Ω load, or 30W per channel into an 8Ω load.
