PRODUCTION DATA.
The edge rate of the Class-D output is controllable via I2C field EDGE_RATE in register EDGE_ISNS_BOOST. This allows users the ability to adjust the switching edge rate of the Class-D amplifier, trading off some efficiency for lower EMI. Table 13 lists the typical edge rates. The default edge rate of 14 ns passes EMI testing. The default value is recommended but may be changed if required.
