Description
The Si1120 is a low-power, reflectance-based proximity and ambient light
sensor with advanced analog signal processing and analog PWM output.
It includes an integrated differential photodiode, signal processor, and
LED driver. Proximity sensing is based on the measurement of reflected
light from an external, optically-isolated, strobed LED. A separate visible
light photodiode is used for ambient light sensing. The standard package
for the Si1120 is an 8-pin ODFN.
