Description

The ISL29003 is an integrated light sensors 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.

In normal operation, power consumption is less than 300µA. Furthermore, an available software power-down mode controlled via the I2C interface reduces power consumption to less than 1µA.

The ISL29003 supports a hardware interrupt that remains asserted low until the host clears it through I2C interface.

Designed to operate on supplies from 2.5V to 3.3V, the ISL29003 is specified for operation over the -40°C to +85°C ambient temperature range.

Applications

    • Ambient light sensing
    • Backlight control
    • Temperature control systems
    • Contrast control
    • Camera light meters
    • Lighting controls
