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 SMD tip
TAS5613 CLASS D 300W AMPLIFIER CIRCUIT
TDA9859 with I2C-bus control is usedon the Digital Preamp floor VOLUME, MUTE, INPUT, BASS, TREBLE, EFFECT, SHUTDOWN controls are made on the LCD (LC7981) screen with buttons. The TDA9859 has source codes prepared with AVR Studio 4 software that does this with ATmega128 microcontroller communication.
