In world of modern advancements, there are millions of equipment and integrated circuits that make the complicated life much easier. Several integrated circuits are compiled together to design the amplification of a sound system. Sound systems can be made louder or amplified in a number of ways. One way of increasing the energy of the sound system is to make the small currents larger and sent to the loudspeaker system where they are converted into the much larger vibrations of the speaker cone. Due to attenuation and various interruptions of the input signals, the received signals become disrupted. For this reason, the integrated circuit used must be have lower noise levels and higher amplifications. This paper introduces a simple amplifier circuit which can be used both as inverting and non-inverting ways. TDA2030 is the IC that acts as an AB class amplifier. A modified amplifier circuit is proposed is this paper using TDA2030 which is also cheaper than other ICs.
