TECHNICAL DATA
KIA6281H
BIPOLAR LINEAR INTEGRATED CIRCUIT
5.8W DUAL AUDIO POWER AMPLIFIER.
22W BTL AUDIO POWER AMPLIFIER.
The KIA6281H is dual audio power amplifier
for consumer application.
It is designed for high power, low distortion and
low noise.
It also contains various kind of protectors.
It is suitable for car-audio power amplifier with
high performance.
