TDA7057AQ datasheet by Philips Semiconductors

TDA7057AQ Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the TDA7057AQ?
  The maximum power dissipation of the TDA7057AQ is 1.4W, but it can be increased to 2.5W with proper heat sinking.
• How do I ensure the amplifier is stable and doesn't oscillate?
  To ensure stability, a bypass capacitor of at least 10nF should be connected between the supply pins (VCC and GND) as close to the IC as possible. Additionally, the layout should be designed to minimize parasitic inductance and capacitance.
• What is the recommended operating voltage range for the TDA7057AQ?
  The recommended operating voltage range for the TDA7057AQ is 3V to 12V, with a typical voltage of 6V or 9V.
• How do I configure the gain of the amplifier?
  The gain of the amplifier can be configured by selecting the appropriate values for the external resistors R1 and R2. The gain can be calculated using the formula: Gain = (R2 / R1) + 1.
• What is the maximum output current of the TDA7057AQ?
  The maximum output current of the TDA7057AQ is 100mA, but it can be increased to 200mA with proper heat sinking and a sufficient power supply.
