| NTE1288 Integrated Circuit Audio Power Amplifier, 10W for Car Radio Description: The NTE1288 has improved performance with the same pin configuration as the NTE1232. The additional features of the NTE1232; very low number of external components, ease of assembly, space and cost saving, are maintained. The device provides a high output current capability (up to 3.5A), very low harmonic and cross distortion. Complete safe operation is guaranteed due to protection against DC and AC short-circuit between all pins and GND, thermal over-range, load dump voltage surge up to 40V, polarity inversion and fortuitous open ground.
