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