Hi Fi Amplifier Circuit – 2X12 Watts

Description.

Here is the circuit of a 2X12 watt H iFi  amplifier circuit using IC TDA 2616 from Phillips.A quiet simple and robust circuit using very less components.This makes the circuit ideal for a portable power amplifier.The circuit delivers 12 Watts power on  8 Ohm speaker for each channel at +/- 12 V dual supply.

The TDA2616 is a  stereo power amplifier IC comes  in a 9-lead single-in-line (SIL9) plastic power package (SOT131). This IC is  specially designed for mains fed amplifier circuits, such as stereo radio,tape  and television .The IC has good gain balance of both channels and Hi-fi in accordance with IEC 268 and DIN 45500 standards.Also the IC TDA 2616 has special inbuilt circuit for the  suppression of noise signals at the inputs, during switch-on and switch-off.This prevents click sounds during power on and power off.

Notes.

  • All capacitors except C10 & C9 are ceramic.
  • All 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.

    Hi if i just use normal 12v – 1A power supply adapter. And attach its positive to +12v and negative to -12v of your circuit. Will it work without giving noise.
    On standby when we haven’t connected anything to the input mostly circuits like this gives huge noise. I add potentiometer but nothing happens to make hum sound low. Can you please help me????

    I am tried this amp.
    But it sound is not clear it continous cracking .
    So help how can i overcome it

      hi .. This Ranjan from bangladesh ..
      this is so simple circuits .. pls cheak this circuits without veritable resistor , and must use 220nf for input , and 8.2 ohm sires with 22nf capacitor .

      it must working and this time i am listening a song using this amplifier

    i have two woofers of 70 watt what type of amplifier i should need 70 watt or 140 watt ???

    This is good for about 7Wrms into 8ohms with a 12V supply. With a 16V split supply, this chip makes 12W into 8 ohms at .5% THD. C9 & 10 need only be 25 Volts. R1 & 2 should be about 2 ohms. Definately need a 4 sq in or larger heatsink.
