TDA7269A datasheet by STMicroelectronics

TDA7269A Frequently Asked Questions (FAQs)

• What is the recommended power supply decoupling for the TDA7269A?
  A 10uF capacitor in parallel with a 100nF capacitor between the power supply pins (VCC and GND) is recommended for proper decoupling.
• How do I ensure the TDA7269A is stable and doesn't oscillate?
  Ensure that the gain-setting resistors (Rf and Ri) are properly matched, and the input and output capacitors (Ci and Co) are of sufficient value to prevent oscillation.
• What is the maximum power dissipation of the TDA7269A?
  The maximum power dissipation of the TDA7269A is 2.5W, and it is recommended to keep the junction temperature below 150°C to ensure reliability.
• Can I use the TDA7269A as a bridge-tied load (BTL) amplifier?
  No, the TDA7269A is not designed for BTL operation. It is intended for single-ended output applications only.
• How do I mute the TDA7269A?
  The TDA7269A has a built-in mute function. To mute the amplifier, pull the MUTE pin high (VCC) to disable the output stage.
