Light-to-Digital Output Sensor with High
Sensitivity, Gain Selection, Interrupt
Function and I
2
C Interface
The ISL29013 is an integrated light sensor with I
2
C
interface. It has an internal signed15-bit integrating type
ADC designed based on the charge-balancing A/D
conversion technique. This ADC is capable of rejecting 50Hz
and 60Hz flicker caused by artificial light sources. The lux
range select feature allows the user to program the lux range
for optimized counts/lux.
In normal operation, power consumption is typically 250碌A.
Furthermore, a power-down mode can be controlled by
software via the I
2
C interface, reducing power consumption
to less than 1碌A.
The ISL29013 supports a hardware interrupt that remains
asserted low until the host clears it through I
2
C interface.
Designed to operate on supplies from 2.5V to 3.3V, the
ISL29013 is specified for operation over the -40掳C to +85掳C
ambient temperature range.
