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.

NOTES:
1. Please refer to TB347 for details on reel specifications.
2. 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.
3. For Moisture Sensitivity Level (MSL), please see device
information page for ISL29010. For more information on MSL
please see tech brief TB477.
