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.
TAS5611A CLASS D AMPLIFIER CIRCUIT
The 32v and 12v voltages required for operation of the system have about 400W of power provided by the TL494 SMPS circuit . SMPS circuit design As with ATX power supplies, only an ETD49 core with different power traces is used
TL494 CLASS D AMPLIFIER SMPS CIRCUIT
In addition, the Class D Amplifier project features the LM3615 vu meter circuit and the TDA1524 preamp tone control circuit. These parts are working with 12V.
