12-CHANNEL ACTIVE PHOTOSENSOR ARRAY

Rev C3, Page 1/8

FEATURES

o Monolithic array of independent photosensors with excellent

matching

o Compact photosensor size of 800 µm x 300 µm enabling

high-quality encoder scanning at reduced system dimensions

o Narrow track pitch of 0.42 mm cuts down illumination efforts

o Enhanced EMI immunity due to on-chip pre-amplification

o Dark current compensation permits high temperature

operation

o Open-collector outputs as highside current source

o Simple gain setting and current-to-voltage conversion by

external load resistors

o Single supply operation from 4 V to 5.5 V

o Low power consumption

o Space saving, RoHS compliant optoQFN and optoBGA

packages

o Options: extended temperature range of -40 °C to 125 °C,

customized COB modules, reticles and code discs

APPLICATIONS

o Optical position encoding from

analog sine/cosine signals

o Incremental encoders with index

signal

o Motor commutation encoders
