TDA2613 Hi Fi audio amplifier
A 6 watt audio amplifier circuit using TDA2613 is shown here. TDA2613 is an integrated Hi-Fi audio amplifier IC from Philips Semiconductors. The IC is switch ON / switch OFF click proof, short circuit proof, thermally protected and is available in 9 pin single in line plastic package.
In the given circuit, TDA2613 is wired to operate from a single supply. Capacitor C4 is the input DC decoupler while capacitors C5, C6 are power supply filters. Input audio is fed to the non inverting input through capacitor C4. Inverting input and Vp/2 pins of the IC are tied together and connected to ground through capacitor C3. Capacitor C2 couples the speaker to the ICs output and the network comprising of capacitor C1 and resistor R1 improves the high frequency stability.

plz wat z dat IN? iz zit d input?
hi is it 220nf or 220uf (c4)
Input capacitors cannot be so high as input impedance is normally high. it should be 220nF.
how to vary the volume
Use a 10K potentiometer in the input between C4 and input socket. Use the following circuit as guide
You have a mistake on shema, the correct value for C4 is 220nf and not 220µf.
as mentioned on constructor datasheet.
can’t i give a supply of less than 12 volt supply?
around 6 to 9 volts
******22nf…&…680uf capasetor r not found in the markets.Have any recovery capasetor 4 this circuits..??***plzzzz help me****
well am impressed with the tda 2613 amp!
Hi Mike very low distortion & noise very low volume to 6watts. good Hi Fi amp you have to listen to believe.
how is d performance of this 6watts hi fi ampli?
You can connect a DC power supply positive to pin7 of the IC and 0 volt (-ve) to pin 5 of the IC (single 24volt supply capable of 1amp current), ensure the voltage is not greater than 24volt DC with 8 ohms speaker
how bout where to connect to transformer ?, i dont see it on d cercuit ,help
