EDGE MODE

To reduce the radiated emissions from the

SSM3582

amplifier,

an edge rate control mode is available. Register 0x05, Bit 3,
controls the edge rate of the switching. This low electromagnetic
interference (EMI) mode is enabled by default. To disable the
low EMI mode, set Bit 3 of Register 0x05 to 0. To return to the
low EMI mode, set Bit 3 of Register 0x05 to 1.

MONO OPERATION

The board is configured for stereo operation by default, but can
be changed to mono operation.
For mono operation, the R27 through R30 resistors must be
fitted with 0 Ω or use 16 AWG wires to short the OUTL+ terminal
to the OUTR+ pin, and, similarly, to short the OUTL− terminal
to the OUTR− pin. Note that the device must be configured to
mono operation by setting the MONO bit (Bit 4, Register 0x04) to
0 before turning on the power stage.

Set this bit by writing Register 0x04 with the hexadecimal value,
0xB1. This ensures the power stage turns on in mono operation.

COMPONENT SELECTION

Selecting the proper capacitors and ferrites for the evaluation
board is key to achieving the performance required at the cost
budgeted.

Output Shunting Capacitors

There are four output filter capacitors, C1, C2, C39, and C40, that
work with the L2, L3, L6, and L7 ferrite beads. Use small size
(0603 or 0402), multilayer, ceramic capacitors of dielectric type
X7R or COG (NPO) materials. The recommended value of the
capacitors is 220 pF.

Output Ferrites

If ferrite beads are preferred for EMI filtering at the output
nodes, Table 1 shows the recommended components to avoid
excessive noise induced by the nonlinear behavior of ferrite
beads.
