FEATURES
APPLICATIONS
♦ Monolithic array of independent photosensors with excellent
matching
♦ Compact photosensor size of 800 µm x 330 µm enabling
smaller encoder systems
♦ Optical position encoding from
analog sine/cosine signals
♦ Incremental encoders with
interpolation
♦ Moderate alignment tolerance due to a track pitch of 1.08 mm
♦ Ultra low dark currents for operation to high temperature
♦ Low noise amplifiers with high transimpedance of typ. 4 MΩ
♦ Short-circuit-proof, low impedance voltage outputs for
enhanced EMI tolerance
♦ Absolute position encoders
using nonius scales
♦ Low power consumption from single 5 V supply
♦ Operational temperature range of -40 to 125 °C
♦ Space saving 15-pin optoBGA package (RoHS compatible)
♦ Available options
PACKAGES
- reticle assembly, code discs
- customized COB modules
