2X100W CLASS D AMPLIFIER CIRCUIT TL494 SMPS POWER SUPPLY SCHEMATIC CIRCUIT DIAGRAM

Although the TAS5611A Class D amplifier with analogue input is used in the Stereo 100W + 100W Class D amplifier project , it is possible to supply 2 channels of 105w with 4-ohm speaker even though it is in the 64-Pin QFP sheath. TAS5611A working voltage from 16v … 34v single source DC .. writes TAS5611A using 32V DC which is normal according to datasheet information.
