DESCRIPTION
The LX1704 family represents a
new generation of a fully integrated
audio stereo Class-D amplifier from
Microsemi. This CMOS stereo Class-
D amplifier series is optimized for low
voltage, low power operation and
minimum system cost. The products
are ideal for use in battery powered
applications where low power consumption
is desirable such as: portable speakers,
DVDs, PMP, and other low power
systems.
The LX1704 family provides very
low quiescent current consumption
through the use of a proprietary output
modulation scheme. This technology
enables filterless operation in many
applications. The part features on board,
low
Rdson,
complementary
output
MOSFET’s that reduces the need for
external components.
The LX1704 is offered in a small
footprint, low profile, 4mm x 4mm 16-
pin MLPQ.
