IC amplifier 18 watt circuit is an IC number HA13118 Hitachi Hard. That the IC will be integrated amplifiers, class AB. And this cycle is to use a bridge circuit. As a result, growth rates up to 55 dB. And pressure from 8-18 volt the current 1-2 amps, with less than 0.2% distortion at 1W. And response. frequencies from 30 Hz-30 kHz.

Amplifier ic 18W using HA13118

When entering the power supply circuit, and paid into the audio input. The audio is through VR1 adjusts the level of the audio signal. And pass the C1 coupling signal. The C2 eliminate the interference. From the audio signal to be sent through to the input pin on pin 3 of IC1. That this circuit to circuit in the form of bridge circuits or extension of the left navigation. And right channels together, to get a higher watt power. The observations from the pin 15 which is the output of left channel speakers are connected to one side. And the other side of the speakers are connected to the output of pin 8, which is the output of the right. The C7 and C8 acting feedback signal to the circuit’s frequency response is better. The C9, C10, R1 and R2 will serve removed the devices. And C11, C12 serve to filter the light properly to prevent any noise shock.
