ACTIVE
WITH INTEGRATED DIGITAL DIAGNOSTICS
MULTIPOWER BCD TECHNOLOGY
MOSFET OUTPUT POWER STAGE
has a very low distortion allowing a clear powerful
sound. Among the features, its superior efficiency
performance coming from the internal exclusive
structure, makes it the most suitable device to simpli-
fy the thermal management in high power sets.The
dissipated output power under average listening con-
dition is in fact reduced up to 50% when compared to
the level provided by conventional class AB solu-
tions.
This device is equipped with a full diagnostic array
that communicates the status of each speaker
through the I
possibility of driving loads down to 1Ω paralleling the
outputs into a single channel. It is also possible to dis-
able the I
the usual ST-BY and MUTE pins.
