Page 3: Overview
User manual for MA evaluation boards EVAL_AUDIO_MA2304DNS_B and EVAL_AUDIO_MA2304PNS_B Overview Overview The demonstration board EVAL_AUDIO_MA2304xNS_B is an evaluation and demonstration board for MERUS™ audio’s MA2304DNS and MA2304PNS amplifiers. It contains digital input/output (I/O) and a variety of output and setup/selection features. It also contains one onboard buck power supply generator (1.8 V/3.3 V selectable) so only one external power supply (PVDD) is necessary. -

Page 12: Measurement Methods
User manual for MA evaluation boards EVAL_AUDIO_MA2304DNS_B and EVAL_AUDIO_MA2304PNS_B 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 13 User manual for MA evaluation boards EVAL_AUDIO_MA2304DNS_B and EVAL_AUDIO_MA2304PNS_B Measurement methods Figure 7 shows an example measurement setup using an 8 Ω/22 µH load, similar to the setup shown in Figure Figure 7 Audio measurement setup example Figure 8 shows an example dynamic range measurement performed with the previous measurement setup.
