A 6 watt Hi Fi Audio amplifier TDA2613 . TDA2613 is an integrated hi-fi amplifier IC from Philips Semiconductors. HF is on / off test, click, short-circuit proof, thermal protection and is offered in 9-pin single in line package of plastic.
In the given circuit, TDA2613 connected to the control of a supply. Capacitor C4 is the DC input, while decoupler capacitors C5, C6 are the filters of the power supply. Audio is fed to the non-inverting input through capacitor C4. Inverting input and Vp / 2 pins of the IC are connected along and grounded through capacitor C3. Capacitor C2 couples the speaker to the output of integrated circuits and the network comprising capacitor C1 and resistor R1 improved high frequency stability.
