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.
