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. In

addition, the I2C interface 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 via the I2C

interface reduces power consumption to less than 1μA.

The ISL76683 supports twin (upper & lower) user programmed

thresholds and provides a hardware interrupt that remains

asserted low until the host clears it via the I2C control interface.

Designed to operate on supplies from 2.5V to 3.3V, the ISL76683 is

qualified to AEC Q100 and specified for operation over 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.
