IC-PNH series phased array nonius encoders rev c4, page 2/ 10 description the IC-PNH device series represents advanced op- tical encoder ics featuring monolithically integrated photosensors arranged as an hd phased array , pro- viding excellent signal fdelity at relaxed alignment tolerances. its precision sine/cosine output signals allow for a high-resolution interpolation by subsequent devices: depending on the IC-PNH version, a singleturn po- sition can be resolved with up to 24 bit utilizing the 3-channel nonius interpolation of ic-mn. the typical application of IC-PNH devices are abso- lute position encoders for motion control and drive applications. IC-PNH scans 5 tracks in total, whereof 3 analog tracks feature phased-arrays of multiple photosen- sors each per track, generating positive and negative going sine signals, as well as positive and negative going cosine signals. an excellent matching and com- mon mode behavior of the differential signal paths is obtained by a paired amplifer design. due to a typical transimpedance gain of 1 m ? , the output signal level reaches a few hundred millivolts already at low light conditions. additional 2 digital tracks are implemented for sector detection, to separate a repeated nonius scale. for instance, the standard code discs made for IC-PNH feature two nonius scales per turn and provide a 2-bit gray code to distinguish this. sector detection can be used already at low supply voltages from 1.6 v up; the power consumption is low unless other sections are biased. full operation requires a single-sided supply of 4.1 v to 5.5 v.
