TDA7263 datasheet by STMicroelectronics

TDA7263 Frequently Asked Questions (FAQs)

• What is the recommended power supply decoupling capacitor value for the TDA7263?
  A 100nF to 1uF ceramic capacitor is recommended to decouple the power supply pins (VCC and GND) to reduce noise and ensure stable operation.
• How do I ensure the TDA7263 operates within its safe operating area (SOA)?
  To ensure SOA, keep the output power below the maximum rating (20W), maintain a minimum load impedance of 4 ohms, and avoid excessive temperature increases (above 150°C).
• What is the purpose of the bootstrap capacitor (CB) in the TDA7263?
  The bootstrap capacitor (CB) is used to generate a voltage supply for the high-side driver, allowing the output stage to swing close to the positive supply rail, increasing the amplifier's output voltage swing.
• How do I configure the gain of the TDA7263?
  The gain of the TDA7263 can be configured by selecting the appropriate feedback resistors (Rf and Ri) and input capacitors (Ci) according to the desired gain and frequency response.
• What is the maximum allowed output current of the TDA7263?
  The maximum allowed output current of the TDA7263 is 3.5A peak, which corresponds to a maximum output power of 20W into a 4 ohm load.
