100 Watts Amplifier Circuit Diagram. This 100 watt audio amplifier circuit is easy to design and has mute stand by options. If you want to make a hi fi 100w high power stereo audio amplifier then you can use this ic.
The stk4221ii ic from is a dual high power amplifier chip preferably suited for compact high power audio applications for example in cars and luxury transport vehicle. For a mono 100 watt amplifier the power supply could be rated at 1 5a for stereo this needs to be doubled at 3 amps and in case a quadraphonic amplifier is required then make sure to use transformer rated to handle a minimum of 6 amp. Stk4231 is a hybrid thick film ic manufactured by sanyo electric co.
At the beginning of the first stage amplification a filter section blocks unwanted frequency noises.
In this article we explain about 100 watt transistor based amplifier for this circuit 2sc5200 and 2sa1943 transistors are used for mono amplifier board making both. The stk4221ii ic from is a dual high power amplifier chip preferably suited for compact high power audio applications for example in cars and luxury transport vehicle. Tri band amplifier circuit project the tri audio amplifier has three in one an amplification act drive specifically each audio speaker. This 100 watt audio amplifier circuit is easy to design and has mute stand by options.
