Light-to-Digital Output Sensor with High
Sensitivity, Gain Selection, Interrupt
Function and I
The ISL29013 is an integrated light sensor with I
Compatible) 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 250µA.
Furthermore, a power-down mode can be controlled by
software via the I
to less than 1µA.
The ISL29013 supports a hardware interrupt that remains
asserted low until the host clears it through I
Designed to operate on supplies from 2.5V to 3.3V, the
ISL29013 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.
