PRODUCTION DATA
All parameters are measured according to the conditions described in the Section 6.3 .
Most audio analyzers do not give correct readings of Class-D amplifiers’ performance due to the amplifiers sensitivity to out of band noise present at the amplifier output. AES-17 + AUX-0025 pre-analyzer filters are recommended to use for Class-D amplifier measurements. In absence of such filters, a 30kHz low-pass filter (10? + 47nF) can be used to reduce the out of band noise remaining on the amplifier outputs.
