300W CLASS D AMPLIFIER CIRCUIT SMPS DIGITAL PREAMP SCHEMATIC CIRCUIT DIAGRAM

Class D Amplifier project used TAS5613 class amplifier integrated BTL mode 2 × 150 and mono 300w power can be used in the project 2X150W used TAS5613 working voltage 18v … 38v dc (asymmetric) writer used DC 30v. Integral has 44-pin PSOP3 and 64-Pin QFP sleeves Coil, large capacitors, etc. on QFP type PCB used in the project. all materials except the SMD tip.

The goal of audio amplifiers (class d amplifiers) is to faithfully, efficiently, and with low distortion reproduce input audio signals at sound-producing output elements at desired volume and power levels. Because audio frequencies range from about 20 Hz to 20 kHz, the amplifier’s frequency response must be good across this range (less when driving a band-limited speaker, such as a woofer or a tweeter). Power capabilities range from milliwatts in headphones to a few watts in TV or PC audio, tens of watts in “mini” home stereos and automotive audio, and hundreds of watts and beyond for more powerful home and commercial sound systems—and to fill theatres or auditoriums with sound.
