7.5 Electrical Characteristics
At V_CC = 3.0 V to 5.5 V and T_A = –40°C to 85°C, VLED = 5.0 V; Typical values are at V_CC = 3.3 V, T_A = 25°C (unless
otherwise noted).

(1) The deviation of each output in same color group (OUTR0~15 or OUTG0~15 or OUTB0~15) from the average of same color group
constant current. The deviation is calculated by the formula. (X = R or G or B, n = 0~15)
