GENERAL DESCRIPTION
The EVAL-SSM3582Z is the evaluation board for the
, integrated stereo, 31.76 W, high efficiency,
Class D, audio amplifiers with a digital input. This evaluation
board can be used for both the
devices.
The application circuit requires few external components and
can operate from a single 4.5 V to 16 V supply. The EVAL-
SSM3582Z is capable of delivering 14.67 W 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
feature 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
or the
operate with 93.8% 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 EVAL-
SSM3582Z, the
have a typical
noise floor of 38.5 μV rms A weighted.
This user guide describes how to configure and use the EVAL-
SSM3582Z. Read this user guide in conjunction with the
and the
data sheets, which provide specifications,
internal block diagrams, a register map, and application
guidance for the amplifiers.
