INTRODUCTION
The iC-PZ is an EncoderBlue
cal encoder IC featuring integrated HD Phased Array
photosensors and a blue LED in an OptoQFN32 pack-
age. It is designed for high-resolution absolute position
measurement without the need for highly accurate align-
ment of each encoder system. To achieve this goal,
numerous automatic calibrations are implemented.
