| NTE1115 & NTE1115A Integrated Circuit Audio Power Amplifier, 7W Description: The NTE1115 and NTE1115A are monolithic integrated circuits designed for use as low frequency class B amplifiers. These devices provide 7W power output at 16V/4, 6W at 14.4V/4, 2.5W at 9V/, 1W at 6V/4 and works with a wide range of supply voltages (4V to 20V); and gives high output current (up to 2.5A), high efficiency (75% at 6W output), very low harmonic and cross-over distortion. In addition, thermal protection is provided.
