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 [...]
A very useful audio amp in an 8-pin DIL package. The IC features a very low minimum working supply voltage of 3V, low quiescent current, good ripple rejection, no crossover distortion and low power dissipation. Maximum supply voltages is 16 Volts into 16 Ohms speaker, 12Volts into 8 Ohms and 9Volts into 4 Ohms. Related [...]
This is power amplifier OTL circuit,It is old but good amp(classic) I like it. It is have power output 60W at 8ohm speaker. I use IC op-amp LM3900 is mian part in this circuit. The LM3900 function amp audio signal,ad have transistor 2N3055 x3 for boost power sound audio. The voltage power used 70V at [...]
