The IC 10W +10 W stereo amplifier circuit design that looks similar to the IC 8W +8 W stereo amplifier circuits of the previous album.But it will change the IC amplifier as a number TDA2009.Within the IC for circuit amplifiers, Hi-Fi class AB.And output short circuit protection sectors as well.But there will be different according [...]
This circuit uses a stereo amplifier IC in a 14-pin DIL package that requires very few external components to make a complete 2 Watt per channel power amplifier. The LM1877N-9 is suitable for use with 8ohm or 16ohm speakers.[...] Related Links More circuit about stereo amplifier More circuit about Power Amplifier IC TDA1908 Amplifier CAR [...]
Tr1 and Tr2 transistors funcitons as direct coupled voltage amplifiers. R6 resistor, D1 and D2 diodes determine the standby current of complement driver stage (Tr3/Tr4) and output stage (Tr5/Tr6). C3, C5, C6 and R3 help keeping stability. Amplifier’s input sensitivity is 400mA at 4 ohm load and 12V supply and 600mV at 8 ohm load [...]
