Intersil ISL29004
The ISL29004 is an integrated light sensor with a 16-bit integrating type ADC, I2C user programmable Lux range select for optimized counts/Lux, and I2C multi-function control and monitoring capabilities. The internal ADC provides 16-bit resolution while rejecting 50Hz and 60Hz flicker caused by artificial light sources. The device also support a hardware interrupt that remains asserted low until the host clears it through I2C interface.| Part No. | ISL29004 |
