| TECHNICAL DATA 10W AUDIO AMPLIFIER DESCRIPTION The main features of KKA2003, are very low number of external components, easy of assembly, space and cost saving. The device provides a high output current capability (up to 3.5A), very low harmonic and cross-over distortion. Completely safe operation is guaranteed due to protection against DC and AC short circuit between all pins and ground, thermal over-range, load dump voltage up to 40V and open ground.
