Rev E1, Page 2/11
DESCRIPTION
The iC-PN device series represents advanced opti-
cal encoder ICs featuring monolithically integrated
photosensors arranged as an HD Phased Array, pro-
viding excellent signal fidelity at relaxed alignment
tolerances.
Precise sine/cosine output signals allow for a high-res-
olution interpolation by subsequent devices: depend-
ing on the iC-PN version, a singleturn position can
be resolved with up to 23 bit utilizing the 3-channel
nonius interpolation of iC-MN.
The typical application of iC-PN devices are abso-
lute position encoders for motion control and drive
applications.
The iC-PN scans 3 incremental tracks by a phased-ar-
ray of multiple photosensors each per track, and gen-
erates positive and negative going sine signals, as
well as positive and negative going cosine signals. An
excellent matching and common mode behavior of
the differential signal paths is obtained by a paired
amplifier design. Due to a typical transimpedance
gain of 1 MΩ, the output signal level reaches a few
hundred millivolts already at low light conditions.
