12-CHANNEL ACTIVE PHOTOSENSOR ARRAY
Rev C1, Page 1/7
FEATURES
APPLICATIONS
♦ Monolithic array of independent photosensors with excellent
matching
♦ Optical position encoding from
analog sine/cosine signals
♦ Incremental encoders with index
signal
♦ Compact photosensor size of 800 µm x 300 µm enabling
high-quality encoder scanning at reduced system dimensions
♦ Narrow track pitch of 0.42 mm cuts down illumination efforts
♦ Enhanced EMI immunity due to on-chip pre-amplification
♦ Dark current compensation permits high temperature
operation
♦ Motor commutation encoders
♦ Open-collector outputs as highside current source
♦ Simple gain setting and current-to-voltage conversion by
external load resistors
♦ Single supply operation from 4 V to 5.5 V
♦ Low power consumption
PACKAGES
♦ Space saving, RoHS compliant optoQFN and optoBGA
packages
♦ Options: extended temperature range of -40 to 125 °C,
customized COB modules, reticles and code discs
14-pin optoBGA
