Hi-Fi Amplifier Circuit

hifi amplifier circuit tda2616

Working & Description:

  • Circuit delivers 12 Watts power on  8 Ohm speaker for each channel at +/- 12 V dual supply.
  • K1 & K2 are speakers on pins 4 & 6
  • 3 and 8 are grounded
  • 1 and 9 are left and right inputs
  • 5 and 7 are provided voltages
  • Circuits consist of capacitors and resistors combination.

Tips for better results:

  • Use ceramic capacitors.
  • Capacitors must be rated 50V.
  • Use a well-regulated and filtered +/- 12 V dual power supply that is able to provide at least 2 A continuous current.
  • Use PCB of good quality
