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

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

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

SSM3582

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

and the

SSM3582

have a typical noise floor of 38.5 μV rms A weighted.

This user guide describes how to configure and use the

SSM3582

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.
