ISL29010
FN6414.0
Light-to-Digital Output Sensor with High
Sensitivity, Gain Selection, and I2C
Interface
The ISL29010 is an integrated light sensor with I2C
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 250µA.
Furthermore, a power-down mode can be controlled by
software via the I2C interface, reducing power consumption
to less than 1µA.
Designed to operate on supplies from 2.5V to 3.3V, the
ISL29010 is specified for operation over the -40°C to +85°C
ambient temperature range.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets; molding compounds/die attach
materials and 100% matte tin plate - e3 termination finish, which is
RoHS compliant and compatible with both SnPb and Pb-free
soldering operations. Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
