The bypass pin capacitor (Cb) gives a filtering of half-supply.The supply bypass capacitor (Cs) gives the filtering of the power supply.

The feedback resistance (Rf) fixes the gain of closed-loop within conjunction through Ri.In addition, it creates an HPF using Ri on fc = 1/(2πRi*Ci). An input coupling capacitor (Ci) blocks the voltage of DC where the i/p of an amplifier ends.This resistor can form an HPF ( high pass filter) using the input coupling capacitor (Ci) on fc = 1/(2πRi*Ci). An inverting input resistance (Ri) sets the gain of closed-loop within conjunction through feedback resistance (Rf).The main components used in this circuit are Ri, Ci, Rf, Cf, and Cb which are discussed below. The gain of the primary op-amp is configurable externally whereas the second amplifier is fixed internally in inverting configuration with a unity gain. This circuit can be built with two operational amplifiers with different configurations. The circuit diagram of this audio amplifier is shown below. This IC is the best choice for those who are looking for dual op-amp IC including wide bandwidth as well as high gain. It is used in an audio speaker as well as low-voltage applications. This amplifier doesn’t use capacitors like output coupling otherwise bootstrap. The main intension of this IC is to offer output power with high-quality using fewer components. This type of amplifier has a feature like a shut-down mode. Alternatives ICs of MD8002A audio amplifier are AD620, LM386, JRC45558 & IC6283.An equivalent ICs of MD8002A audio amplifier is LM4871 and TDA2050.The equivalent and alternative ICs of this amplifier include the following. The improved PSSR is 60 dB at 217 Hz and 1kHz.The range of supply voltage is 2V to 6V.This article discusses an overview of the MD8002A Audio Amplifier.

This signal measures a hundred microwatts and generates few watts which is used in small electronic devices like clock radios, a stereo system used in homes, etc.

For instance, an audio amplifier’s input signal is the electric guitar signal. Most of the amplifiers use low-level inputs. The input of the audio amplifier is any audio source such as CD players, record players, cassette players, and digital audio players. In a typical audio playback chain, the audio amplifier is the last electronic stage before the signal is transmitted to the loudspeakers. These amplifiers are applicable in all kinds of sound systems like sound strengthening, home theater system, surround-sound system, audio systems in the home, entertainment center, and guitar amplifiers. An audio amplifier is one kind of electronic amplifier that is used to amplify electronic audio signals which have low power like the output signal from the radio receiver.
