Summary of Arduino 12W Audio Amplifier
This article describes a 12W audio amplifier project centered on the TDA2006 Pentawatt IC, known for high output current and low distortion. The design features comprehensive protection including short-circuit and thermal shutdown systems. It supports an 18V single supply, delivering 12W into 4Ω or 8W into 8Ω loads. The kit includes essential components like a PCB, heatsink, mounting hardware, and connectors for power, audio input, and volume control via a potentiometer.
Parts used in the 12W Audio Amplifier:
- TDA2006 PENTAWATT package
- Power supply up to 18 VDC
- Screw terminal connector
- Header connector for potentiometer
- Power-On LED indicator
- Heatsink for IC
- Four mounting holes with nut and stud
- PCB (51 mm x 63 mm)
Project is built around TDA2006 PENTAWATT package. TDA2006 provide high output current and has very low harmonic cross-over distortion. Further the device incorporate- rates an original (and patented) short circuit protection system comprising an arrangement for automatically limiting the dissipated power so as to keep the working point of the output transistors within their safe operating area. A conventional thermal shutdown system is also included. The TDA2006 is pin to pin equivalent to the TDA2030.
