ELECTRICAL CHARACTERISTICS - FHD MODE
Note:
13. SNR
A
dB is referenced to the output signal amplitude resulting in the specified output power at
THD+N <1%. See “Parameter Definitions” on page 29 for more information.
14. Idle Current Draw (I
IDLE
) is specified without any output filtering. Refer to Section 5.3 on page 17 for
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
Level for Entering VBATT Operation in HD/FHD Modes (V
IN-VBATT
) given in “Electrical Characteristics
- All Operational Modes” on page 9.
