The ISL29012 is an integrated light sensor with I2C (SMBus
Compatible) interface. It has an internal signed 15-bit
integrating type ADC designed based on the
charge-balancing 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 ISL29012 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
ISL29012 is specified for operation over the -40°C to +85°C ambient temperature range.
