The ISL29020IROZ-T7 is a low power high sensitivity Integrated Light Sensor with I2C (SMBus compatible) interface. Its state-of-the-art photodiode array provides close-to human eye response and good IR rejection. This ADC is capable of rejecting 50 and 60Hz flicker caused by artificial light sources. The lux range select feature allows the user to program the lux range for optimized counts/lux. In normal operation, typical power consumption 55μA. In order to further minimize power consumption, two power-down modes have been provided. If polling is chosen over continuous measurement of light, the auto-power-down function shuts down the whole chip after each ADC conversion for the measurement. The other power-down mode is controlled by software via the I2C interface.
