ELECTRICAL CHARACTERISTICS - FHD MODE

Note:

THD+N <1%. See “Parameter Definitions” on page 29 for more information.

information on output filtering. At idle, the output devices will switch at the same rate in HD and FHD

mode. FHD only changes the output switching frequency when the input levels are above the “Input

- All Operational Modes” on page 9.
