The ISL29033 includes a lux range select feature that allows users to program the lux range for optimized sensitivity. Power consumption is extremely low — the typical current consumption is 55uA in operation and 0.01uA in shutdown. The ISL29033 provides a hardware interrupt that remains asserted until the host clears it through the I2C interface. The function of ADC conversion continues without stopping after interrupt is asserted.
