3-CHANNEL SIN/COS PHOTOSENSOR ARRAY

Rev B1, Page 1/7

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 alignment tolerance due to a track pitch of 1.08 mm

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 Low power consumption from single 5 V supply

o Operational temperature range of -40 to 125 °C

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

o Available options

- reticle assembly, code discs

- customized COB modules

APPLICATIONS

o Optical position encoding from

analog sine/cosine signals

o Incremental encoders with

interpolation

o Absolute position encoders

using nonius scales
