PHASED ARRAY NONIUS ENCODER Rev C2, Page 2/10 DESCRIPTION The iC-PNH3348 represents an advanced optical encoder IC featuring monolithically integrated photosensors arranged as an HD Phased Array, providing excellent signal fidelity at relaxed alignment tolerances. Its precision sine/cosine output signals allow a high-resolution interpolation by subsequent devices: a singleturn position can be resolved with up to 24 bit utilizing the 3-channel nonius interpolation of iC-MN. The typical application of iC-PNH3348 are absolute position encoders for motion control and drive applications....
