Light-to-Digital Output Sensor with High
Sensitivity, Gain Selection, and I
2
C
Interface
The ISL29010 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 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(chǔ).
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(chǔ).
Designed to operate on supplies from 2.5V to 3.3V, the
ISL29010 is specified for operation over the -40擄C to +85擄C
ambient temperature range.
