ISL29013 pdf datasheet (Light-

The ISL29013 is an integrated light sensor with I2C (SMBus
Compatible) interface. It has an internal signed15-bit
integrating type ADC designed based on the chargebalancing
A/D conversion technique. This ADC is capable of
rejecting 50Hz 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, power consumption is typically 250μA.
Furthermore, a power-down mode can be controlled by
software via the I2C interface, reducing power consumption
to less than 1μA.
The ISL29013 supports a hardware interrupt that remains
asserted low until the host clears it through I2C interface.
Designed to operate on supplies from 2.5V to 3.3V, the
ISL29013 is specified for operation over the -40°C to +85°C
ambient temperature range.
