Hi-Fi Audio Power Amplifier for experiments and general use
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.
Connection diagram for TDA1521A Amplifier PCB.
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 4
full range speaker pair.
