SSM2211: 1.5W Mini Amplifier Circuit
The following diagram is the schematic diagram of simple and cheap mini amplifier circuit.
The circuit built based SSM2211. I have never heard about this IC before, this IC may be quite difficult to find in the market, so before deciding to make this circuit, you better look for information about availability of this component in the nearest electronics store.
25W Stereo Amplifier with STK4141II
Above diagram is the schematic diagram of stereo amplifier, build based integrated circuit STK4141II. This stereo amp will deliver about 25W power output on each channel. Take a note that a heatsink must be attached to the power IC STK4141II to prevent overheating.
