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 C interface
- Range 1 = 0 lux to 1000 lux
- Range 2 = 0 lux to 4000 lux
provides four user programmable lux sensitivity ranges for
optimized counts/lux in a variety of lighting conditions. The I C

- Range 3 = 0 lux to 16000 lux
- Range 4 = 0 lux to 64000 lux
interface also provides multi-function control of the sensor and
remote monitoring capabilities.
• Human eye response (540nm peak sensitivity)
• Temperature compensated
In normal operation, power consumption is less than 300µA.
Furthermore, a software power-down mode controlled with the
I C interface reduces power consumption to less than 1µA.

• 16-bit resolution
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 C
control interface.
• Adjustable sensitivity: up to 65 counts per lux
• User-programmable upper and lower threshold interrupt
• Simple output code, directly proportional to lux
• IR + UV rejection

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.
• 50Hz/60Hz rejection
• 2.5V to 3.3V supply
• 6 Ld ODFN (2.1mmx2mm)
• AEC-Q100 qualified
