DESCRIPTION
The LX1701 family represents a
new generation of a fully integrated
audio mono class-D amplifier from
Microsemi. This CMOS monolithic
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 cell phones, PDA’s, web tablets
and other low power systems.
The LX1701 family provides very
low
quiescent
current
consumption
through the use of a proprietary output
modulation scheme. This technology
enables filter-less operation in many
applications. The part features on board,
low
Rdson,
complementary
output
MOSFET’s that reduces the need for
external components.
The LX1701 is offered in a small
footprint, low profile surface mountable
16-pin MLPQ package.
