PHASED ARRAY SINE ENCODER
preliminary
FEATURES
o Compact, 5-channel encoder sensor with differential scanning
and analog sine/cosine outputs:
2048 CPR with index, 1 CPR absolute, size â
39 mm
o Phased-array design for excellent signal matching
o Reduced cross talk due to moderate track pitch
o Ultra low dark currents for operation up to high temperature
o Low noise ampliï¬ers with high transimpedance
o Short-circuit-proof, low impedance voltage outputs for
enhanced EMI tolerance
o Space saving optoQFN and optoBGA packages
(RoHS compliant)
o Low power consumption from single 4.5 to 5.5 V supply
o Operational temperature range of -40 to +110 â¦C
o Suitable code disc:
PD2S 39-2048 (glass 1 mm)
OD â
39 mm, ID â
18.0 mm, optical radius 17.5 mm
Rev C1, Page 1/12
