This is high quality audio power amplifier which we constructed for our
audio related experiments. This amplifier is based on NXP’s TDA1521A
integrated circuit and it is capable to deliver 2 ×
6W audio output power with 20V - 25V asymmetrical power source. The
design of this power amplifier is heavily based on the schematic
provided in the TDA1521A datasheet. As an addition we incorporate
headphone output option to this design.
PCB which we designed for this amplifier is 55mm × 65mm and it need separate power supply to drive. For optimal results use this AF amplifier with 12V – 20V regulated DC supply and with 4Ω full range speaker pair.
PCB, schematic and wiring diagram of this project is available to download at google drive.
