(1) Channel to channel relative accuracy is calculated with the following formulas:

ILED_C2C_Mis(ch0_x) = ((I(ch0_x)

– average(I(ch0_RGB), I(ch1_RGB)) / average(I(ch0_RGB), I(ch1_RGB))*100

ILED_C2C_Mis(ch1_x) = ((I(ch1_x)

– average(I(ch0_RGB), I(ch1_RGB)) / average(I(ch0_RGB), I(ch1_RGB))*100

Where:

•

ILED_C2C_Mis(ch0_x) refers to a general driver x inside channel 0, for example: ch0_R refers to the R driver in

channel 0. Similarly, for ILED_C2C_Mis(ch1_x).

•

I(ch0_x) refers to the high current level of a particular driver in channel 0. Similarly, for I(ch1_x).

•

I(ch0_RGB) refers to the sum of the high current levels for the drivers belonging to channel 0. Similarly, for

I(ch1_RGB).

(2) In-channel relative accuracy is calculated with the following formula:

ILED_Mis(chx_y) = ((I(chx_y)

– average(I(chx_RGB))) / average(I(chx_RGB)))*100

Where:

•

ILED_Mis(chx_y) refers to a general driver y inside a general channel x, for example: ch0_R refers to the R driver

in channel 0.

•

I(chx_y) refers to the high current level of a general driver y in a general channel x.

•

I(chx_RGB) refers to the sum of the high current levels of all drivers belonging to a general channel x.

(3) LED drivers can be used as receiving path for: I²C bridge, Sync pin, parallel address setting by external HW.

(4) Relative accuracy. For absolute accuracy, calibration in applications is necessary.
