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. [...]
This circuit is the audio amplifier circuit has a very popular one.This is a simple circuit. Small pieces of equipment. And Watt are high.The circuit uses IC number LM1875, which is under the protection circuit IC output or Too short circuit. And a significant distortion as low as 0.015% at a frequency of 1kHz. This [...]
This is the Hifi power amplifier circuit, will be used TDA2003 ic number. The normal operation of the integrated circuit,the music amplifier for car audio radio sound.Which it uses the supply voltage from 12 volt car battery.But this circuit adapted for use at home by listening to change power supply to 15 volts. This allows [...]
