PRODUCTION DATA.
All typical characteristics for the devices are measured using the bench EVM and an Audio Precision SYS-2722 audio analyzer. A Programable Serial Interface Adaptor (PSIA) is used to allow the I2S interface to be driven directly into the SYS-2722. SPEAKER OUT terminal is connected to Audio Precision analyzer inputs as shown below. There is a differential to single ended (D2S) filter, with 1st order Passive pole at 120 kHz is added. This is to ensure high performance Class-D amplifier sees a fully differential matched loading at its outputs and no degradation in performance measured due to loading effects of AUX filter on Class-D outputs.
