Light-to-Digital Output Sensor with Gain Selection, Interrupt Function and
I
2
C 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 I
2
C interface
provides four user programmable lux sensitivity ranges for
optimized counts/lux in a variety of lighting conditions. The I
2
C
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
I
2
C 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 I
2
C
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
