KEY FEATURES
DESCRIPTION
The LX1702 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 LX1702 features on
board, low Rdson, complementary
output MOSFET’s that reduces the need
for external components.
The LX1702 is offered in a small
footprint, low profile, 4mm x 4mm 16pin MLPQ.

The LX1702 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.
