Ambient Light Sensing
- Dual ALS senses ambient light and provides 16-bit output counts on
the I²C bus directly
proportional to the ambient light intensity.
- Photopic spectral response of ALS1 nearly matches human eye.
- Broadband response of ALS2 supports compensation for spectral
with different types of cover glass.
- Dynamic dark current compensation
- Linear response over the full operating range.
- Senses intensity of ambient light from 0.05 lux to 52k lux with
21bit effective resolution.
- Continuously programmable integration times (6.25ms, 12.5ms, 25ms…
- Precision on-chip oscillator (counts equal 0.1 lux at 100ms
- Programmable interrupt function including independent upper and
detection or threshold based hysteresis for proximity and or ALS.
- Level or Edge Triggered interrupts.
- Proximity persistence feature reduces interrupts by providing
hysteresis to filter
fast transients such as camera flash
