Caution: The evaluation or reference board contains parts and assemblies sensitive to
electrostatic discharge (ESD). Electrostatic control precautions are required when
installing, testing, servicing or repairing the assembly. Component damage may result
if ESD control procedures are not followed. If you are not familiar with ESD control
procedures, refer to the applicable ESD protection handbooks and guidelines.

Page 12: Speaker Load
User manual for MA evaluation boards MA2304DNS/MA2304PNS Operating the demonstration board Speaker load The demonstration board is configured as a filterless amplifier. This means that no LC filter is placed between the amplifier outputs and the load. In normal use the amplifier relies on the inherent inductance of the loudspeaker, so no extra inductance is needed. -

Page 14: Measurement Methods
Measurement methods Measurement methods Setting up a reliable measurement configuration for the MA2304DNS or the MA2304PNS takes a little more effort than for linear amplifiers, and even “regular” switching amplifiers. This is mainly because the MA2304xNS is a filterless amplifier, which means it does not require an external (usually expensive and bulky) LC filter to remove switching residuals. - Page 15 User manual for MA evaluation boards MA2304DNS/MA2304PNS Measurement methods Figure 12 shows an example measurement setup using an 8 Ω/22 µH load, similar to the setup shown in Figure Figure 12 Audio measurement setup example Figure 13 shows an example dynamic range measurement performed with the previous measurement setup.
