ISL76683
Light-to-Digital Output Sensor with Gain Selection, Interrupt Function and
I2C Interface

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.

NOTES:
1. Refer to TB347 for details about reel specifications.
2. These Pb-free plastic packaged products employ special Pb-free material sets; molding compounds/die attach materials and NiPdAu plate - e4 termination
finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), refer to the ISL76683 product information page. For more information about MSL, refer to TB477.
