The ISL29001 is an integrated ambient light sensor with

ADC and I2C interface. With a spectral sensitivity curve

matched to that of the human eye, the ISL29001 provides

15-bit effective resolution while rejecting 50Hz and 60Hz

flicker caused by artificial light sources.

In normal operation, the ISL29001 consumes less than

300µA of supply current. A software power-down mode

controlled via the I2C interface disables all but the I2C

interface. A power-down pin is also provided, which reduces

power consumption to less than 1µA.

The ISL29001 includes an internal oscillator, which provides

100ms automatic integration periods, or can be externally

timed by I2C commands. Both the internal timing and the

illuminance resolution can be adjusted with an external

resistor.

Designed to operate on supplies from 2.5V to 3.3V, the

ISL29001 is specified for operation over the -40°C to +85°C

ambient temperature range. It is packaged in a clear 6 Ld

ODFN package.
