Then after it reaches output, the amplifier needs negative feedback, it is done with components such as R1 and R2 resistors and C2 capacitor. Īfter non-inverting amplification, the signal reaches the output pin4, here we have D1 and D2 diodes for protection of the whole amplifier against the formation of voltage spikes, then the diodes are connected across both power supply ports such as pin5 and pin3.Non inverting pin is our input portion, at this portion R5 and R6 resistors and C6 capacitor, is for non-investing input action by R6 and R5 resistor, which is to attenuate poor higher frequency signals and C6 capacitor is for bypassing the over energy flow towards R6 resistor. When we connect our input signal towards the amplifier circuit, the C1 capacitor acts as the input DC coupling capacitor, it creates a division between signal incoming and R3 resistors are for to create an input impedance at the amplifier. This is a single power supply circuit based Circuit, so the 3rd and 5th pin are connected to the power supply 12-volt dc.TDA2030 IC had 5 pins, 1st pin non-inverting, 2nd pin inverting, 3rd -ve negative power pin, 4th output pin, and 5th +ve positive power pin.
