(1)

VDD must be applied before VLEDA during power on. VLEDA must always be smaller or equal than VDD+0.3 V.

(2)

Active state occurs during ongoing spectral measurement AEN = “1” and power consumption defined without LED

current.

(3)

Idle state occurs when PON = “1” and all functions are disabled.

(4)

Sleep state occurs when PON = “0” and no active I2C communication.
