PROXIMITY FUNCTION

• Built in infrared LED and photo-pin-diode for proximity

function

• 16 bit effective resolution for proximity detection range

ensures excellent cross talk immunity

• Programmable LED drive current from 10 mA to 200 mA

(in 10 mA steps)

• Excellent ambient light suppression by signal modulation

• Proximity distance up to 200 mm

AMBIENT LIGHT FUNCTION

• Built in ambient light photo-pin-diode with close to human

eye sensitivity characteristic

• 16 bit dynamic range for ambient light detection from

0.25 lx to 16 klx

• 100 Hz and 120 Hz flicker noise rejection
