ELECTRICAL CHARACTERISTICS - ALL OPERATIONAL MODES

Note:

6. No external loads should be connected to the LFILT+ net. Any connection of a load to this point may

result in errant operation or performance degradation in the device.

8. When operating in HD or FHD mode and the differential input voltage remains below the input level

generated LDO supply (VLDO).

9. When operating in HD or FHD mode and the differential input voltage is above this input level

10. Refer to Section 5.5 for more information on Thermal Error functionality.
