The ISL76683 is an integrated light sensor with an internal integrating ADC intended for automotive applications. The ADC provides 16-bit resolution and is capable of rejecting 50Hz and 60Hz flicker caused by artificial light sources. The I2C interface provides four user programmable lux sensitivity ranges for optimized counts/lux in a variety of lighting conditions. The I2C interface also provides multi-function control of the sensor and remote monitoring capabilities. In normal operation, power consumption is less than 300μA. Furthermore, a software power-down mode controlled with the I2C interface reduces power consumption to less than 1μA. The ISL76683 supports twin (upper and lower) user programmed thresholds and provides a hardware interrupt that remains asserted low until the host clears it with the I2C control interface. The ISL76683 is designed to operate on supplies from 2. 5V to 3. 3V, and is AEC-Q100 qualified and specified for operation across the -40°C to +105°C (grade 2) ambient temperature range. To achieve this, the ISL76683 is packaged in a special extended temperature clear package.
