GENERAL DESCRIPTION
The
SSM3302
is a fully integrated, high efficiency, stereo Class-D
audio amplifier. The application circuit requires a minimum of
external components and operates from a single 7 V to 18 V supply.
It is capable of delivering 2 × 8 W of continuous output power
into an 8 Ω load (or 2 × 10 W into 4 Ω) with <1% total harmonic
distortion plus noise (THD + N) from a 12 V supply. In addition,
while mono mode is active, a load as small as 2 Ω up to 20 W
continuous output power can be driven by stacking the stereo
output terminals.
Spread spectrum pulse density modulation is used to provide
lower EMI-radiated emissions compared with other Class-D
architectures. The
SSM3302
includes an optional modulation select
pin (ultralow EMI emission mode) that significantly reduces the
radiated emissions at the Class-D outputs, particularly above
100 MHz. The
SSM3302
can pass FCC Class-B emissions testing
with an unshielded 20 inch cable using common-mode choke-
based filtering.

The fully differential input of the
rejection of common-mode noise on the input. The device also
includes a highly flexible gain select pin that only requires one
series resistor to choose any of the five gain options between 9 dB
and 24 dB, with no change to the input impedance. The benefit
of this is to improve gain matching between multiple
devices within a single application compared to using external
resistors to set gain.
This user guide describes how to configure and use the
evaluation board. This user guide should be read in conjunction
with the
SSM3302
internal block diagrams, and application guidance for the
amplifier IC.
