PRODUCTION DATA.
The edge rate of the Class-D output is controllable via I2C register B0_P0_R6[2:0]. This allows users the ability to adjust the switching edge rate of the Class-D amplifier, trading off some efficiency for lower EMI. Table 1 lists the typical edge rates. The default edge rate of 14ns passes EMI testing. The default value is recommended but may be changed if requried.
