Hi All,
Well I am trying to make a Stereo Amplifier out of two LM3875T .
The power supply unit will be something like the below pic so that reduce the crosstalk to as minimum as possible. Is there any formula so that I could calculate the values of C1 & C2 and hence C3 & C3?
The transformer's secondary AC voltage is 2x18 (so the final DC voltage after smoothing would be almost 2x24V). The frequency of the transformer is 50Hz.
Well I will use two 2200uF 50V capacitors between the ground and pins 1 & 4 of the Amplifier chip (as close to chip as possible). Of course those pins are the supply pins of the chip.
So can you guys help me out to find the values for those smoothing caps too?
Thanks.
