Rev B1, Page 1/8
APPLICATIONS
o
Incremental rotary encoders
o
Linear scales
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
