preliminary
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
