Light-to-Digital Output Sensor with Gain Selection,
Interrupt Function and I 2 C Interface
ISL76683
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. In
addition, the I 2 C 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 I 2 C
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 I 2 C 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.
