INCREMENTAL PHOTOSENSOR ARRAY

Rev B1, Page 1/8

FEATURES

o Monolithic array of independent photosensors with excellent

matching

o Compact photosensor size of 800 µm x 330 µm enabling

smaller encoder systems

o Moderate track pitch for reasonable alignment tolerances

o Ultra low dark currents for operation to high temperature

o Low noise amplifiers with high transimpedance of typ. 4 MΩ

o Short-circuit-proof, low impedance voltage outputs for

enhanced EMI tolerance

o Space saving 15-pin optoBGA package (RoHS compatible)

o Low power consumption from single 4.5 V to 5.5 V supply

o Operational temperature range of -40 to 125 °C

o Available options

- reticle assembly, code discs

- customized COB modules

APPLICATIONS

o Incremental rotary encoders

o Linear scales
