Electrical Characteristics (continued)

Limits apply over the full operating ambient temperature range (

−40°C ≤ TA ≤ 85°C) and VIN = 3.6 V, unless otherwise

specified.

LED current sink matching in the low-voltage current sinks (LVLED1 through LVLED3 or LVLED4 through LVLED6) is given as the

maximum matching value between any two current sinks, where the matching between any two low voltage current sinks (X and Y) is

given as (ILVLEDX ( or ILVLEDY) - IAVE(X-Y))/(IAVE(X-Y)) x 100. In this test LVLED1-3 current sinks are assigned to Bank C and LVLED4-6 are

assigned to Bank F.
