TDA2613 Hi Fi audio amplifier

Description.

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.

    hi is it 220nf or 220uf (c4)

      Input capacitors cannot be so high as input impedance is normally high. it should be 220nF.

    You have a mistake on shema, the correct value for C4 is 220nf and not 220µf.
    as mentioned on constructor datasheet.

    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
