I have a some question about STK 412-150 IC
1.is this sterio amp IC?
2.what is a meaning of chennel?( STK 412-150 is 2channel, datasheet said)
single channel=mono? 2chennel=stereio?
3.is this possible build amp from datasheet schematic?
4.how much volt i have to supply?
5.how many ampere need for amp operat?
datasheet said it is 150w+150w what its meaning?( is this total 300w?)

just have to read...
the datasheet is not a great one, otherwise it's a stereo ampli, 2 channels means stereo; the pcb on the datasheet is good for an amplifier...the voltage supply depends on the operating point you choose...so how many watts you want...and for the current...well P=v^2/R...
good luck...

Hi Bayezid
This module contains two amplifiers that can each deliver 150 watts. Therefore you can make a stereo amplifier that gives 150 watts per channel into 6 ohm loads.
For the power supply, you need four voltage rails.
If you want the full 150 watts per channel, you need + & - 57 volts for Vh and + & - 38 volts for Vl. (see the table st the top of page 2 of the datasheet)
You will need two transformers, one rated at 80 volts, centre tapped, 6 amps current rating, the second one rated at 54 volts, centre tapped, 4 amps current rating.
I would suggest increasing the filter capacitors from 10,000 uF to 50,000 uF. The 500 ohm resistors should be rated at 10 watts. (see diagram at top of page three)
Good luck with your project.

Hi everyone!!!
Well, if its not to late.... let me answer your third question!!
Yes you CAN!!!
Of course that you have to consider the four voltages rails that "rpapps" metioned.
I found a transformer from a Sony stereo that has the four volatge rails. I builded the amplifier following the schematic, that it is on the datasheet. And it works!!!!!!
If you still trying to build this amplifier or someone else is planning to build it, Don't hesitate to ask me about your doubts!!
I included some photos!!!

An externally hosted image should be here but it was not working when we last tested it.
