The LX1721/1722 is a monolithic high
performance Class-D stereo controller IC
designed for high efficiency or space
constrained audio requirements such as
portable or battery operated products,
automotive amplifiers, and multi-channel
multimedia computer and video game
applications. This high frequency, full
audio
bandwidth
amplifier controller offers dramatically
improved performance over Linfinity’s
previous generation amplifier products.
Enhancements include higher output
power, better SNR, lower noise floor, and
reduced THD. Combined with output
power MOSFET’s and an output filter, the
LX1721/1722 is a complete Class-D audio
solution.

A complete audio amplifier module is
available to quickly evaluate the LX1721
or LX1722 stereo controller. Simply
connect the amplifier to the power source,
audio signal, and speakers. Reference
designs support a variety of requirements
including
multi
subwoofers, satellite / subwoofer com-
binations and various speaker loads (2
,
4
, 8
). The versatile amplifier solution
can easily be adjusted for frequency
response, optimized for efficiency and
performance, or designed to minimize
PCB area and component count. The
LX1721/1722 is available in a space
saving 44-pin QSOP package.
