GENERAL DESCRIPTION
The
EVAL-SSM3582Z
is the evaluation board for the SSM3582,
an integrated stereo, 31.76 W, high efficiency, Class-D, audio
amplifier with digital input. The application circuit requires few
external components and can operate from a single 4.5 V to 16 V
supply. The
EVAL-SSM3582Z
of continuous output power to a 4 Ω load from a 12 V power
supply, with <1% THD + N, or 31.76 W into a 4 Ω load from 16 V,
10% THD + N.
The
SSM3582
features a high efficiency, low noise modulation
scheme that requires no external reconstruction filter (LC) output
filters. This scheme provides high efficiency, even at low output
power.
The
EVAL-SSM3582Z
and the
efficiency at 10 W into an 8 Ω load or 90.6% efficiency at 18 W
into 4 Ω load from a 12 V supply. The
SSM3582
have a typical noise floor of 38.5 μV rms A weighted.
This user guide describes how to configure and use the
evaluation board. Read this user guide in conjunction with the
SSM3582
data sheet, which provides specifications, internal block
diagrams, a register map, and application guidance for the
amplifier.
