ISL29004
Light-to-Digital Output Sensor with
Address Selection, High Sensitivity, Gain
Selection, Interrupt Function and I

C
Interface
The ISL29004 is an integrated light sensor with a 16-bit
integrating type ADC, I
2
C user programmable Lux range
select for optimized counts/Lux, and I
2
C multi-function
control and monitoring capabilities. The internal ADC
provides 16-bit resolution while rejecting 50Hz and 60Hz
flicker caused by artificial light sources.
In normal operation, power consumption is typically 300µA.
Futhermore, an available software power-down mode
controlled via the I
2
C interface reduces power consumption
to less than 1µA. The device also support a hardware
interrupt that remains asserted low until the host clears it
through I
2
C interface.
The ISL29004 is in an 8 Ld ODFN package and has two I
2
C
address pins for multiple devices on the same bus. The
ISL29003 is a similar light sensor with a hardwired I
2
C
address that is available in ODFN6 package.
Designed to operate on supplies from 2.5V to 3.3V, the
ISL29004 are specified for operation over the -40°C to
+85°C ambient temperature range.
