6 Watt Hi-Fi Audio Amplifier Circuit using TDA2613 IC
6 Watt Hi-Fi Audio Amplifier Circuit using TDA2613 IC: 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 switched ON / switch OFF click proof, short circuit proof, thermally protected and is available in 9 pins single in-line plastic package.
6 Watt Hi-Fi Audio Amplifier Circuit
In the given 6 Watt Hi-Fi Audio Amplifier 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.
