Note
  • Use 18-24V DC for powering the circuit.
  • A proper heat sink is necessary for the IC.
The TDA 1910 IC is a monolithic integrated circuit inmultiwatt package, intended for use in Hi-Fi audio power applications, as high quality TV sets. The TDA 1910 meets the DIN 45500 (d = 0.5%) guaranteed output power of 10W when used at 24V/4W. At 24V/8W the output power is 7W min.
