The
LX1720
is a highly-integrated,
Switching Class-D Stereo Power Am-
plifier Controller IC
with power and
size features that make it ideal for multi-
media computer applications, as well as
other applications where high fidelity
sound is required.
With input voltage ranging from 7V-
15V, the LX1720 is designed to operate
over the full 20Hz to 20kHz audio range.
Signal distortion measurements using
industry standard 1kHz signal yields THD
+ noise levels < 1% (10 watts output).

LX1720
Its high efficiency (>92%) eliminates the
need for heat sinks — even while deliv-
ering more than 10W
across 8 ohms
per channel (20W
RMS
stereo) with 0.1 ohm
SO-8 power FETs.
The LX1720's output power is limited
only by external FETs and available sup-
ply voltage.
While offering breakthrough perfor-
mance capabilities for notebooks, the
LX1720 is equally attractive for multime-
dia systems or to drive full-size home
theatre speakers.

per channel in an area less than 3"x3",
without using expensive heatsinks
I
Greatly reduced power supply
requirements when compared to a linear
solution of same power capabilities
I
Any speakers can be used including
conventional home stereo speakers
I
Very light weight circuitry will not add to
the overall weight of the system
I
Multimedia amplifier can be directly
incorporated on the motherboard using
surface mount components
