INCREMENTAL PHOTOSENSOR ARRAY

Rev D1, Page 1/9

FEATURES

•

Monolithic array of independent photosensors with excellent

matching

•

Compact photosensor size of 800 µm x 330 µm enabling

smaller encoder systems

•

Moderate track pitch for reasonable alignment tolerances

•

Ultra low dark currents for operation to high temperature

•

Low noise amplifiers with high transimpedance of typ. 1 MΩ

•

Short-circuit-proof, low impedance voltage outputs for

enhanced EMI tolerance

•

Space saving optoBGA and optoQFN package (RoHS

compliant)

•

Low power consumption from single 4.1 V to 5.5 V supply

•

Operational temperature range of -40 °C to +125 °C

•

Available options

- reticle assembly, code discs

- customized COB modules

APPLICATIONS

•

Incremental rotary encoders

•

Linear scales
