Summary of 10W STEREO AUDIO AMPLIFIER
This project is a 10W Stereo Audio Amplifier using the Philips TDA1521 IC, designed for high-quality audio output suitable for applications like stereo TV sound and radios. It features a simple design with minimal external components, input muting on power transitions, low output offset, gain balance, short circuit protection, and thermal protection. Operated at an 18V DC supply with a 3.5A current, it delivers 2x10W output power with a frequency response of 20Hz-20kHz and an input impedance of 20k Ohm.
Parts used in the 10W Stereo Audio Amplifier:
- Philips TDA1521 IC
- Power supply (18V DC, 3A recommended)
- Input and output components (resistors, capacitors as per circuit design)
- PCB (Printed Circuit Board)
This project is a 10W Stereo Audio Amplifier based on TDA1521 IC.
