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 based on the LM3876. A 11-pin plastic package IC with high performance audio power amplifier, an output mute function which can be used to eliminate switch-on and switch-off “thumps” to the loudspeaker load. It is capable of delivering 40W continuously into 8ohm load, and is fully protected using established techniques. The output [...]
This The multi-purpose Amplifier using TDA2030. It is have power 8 watt (RMS) at 8 ohm loudspeakers. It is have low noise be valuable THD (Total harmonic distortion) 0.1% , When friends use Power supply Voltage Source 28 Volt at 4 ohm loudspeakers have output power 12Watt. But be high class the noise increases to [...]
