Product Information

The optical encoder iC-PN features monolithically integrated photosensors arranged as a phased-array.

The transimpedance gain of typically 1 MΩ generates output signals of a few hundred millivolts already from an illumination level of 0.5 mW/cm2. In most cases no additional measures must be considered to filter for noise and interferences. The spectral sensitivity range includes visible to near infrared light, with the maximum sensitivity being close to a wavelength of 680 nm.

Analog nonius-scale encoders are the typical application for iC-PN. Its 3-track scanning features a phased-array of multiple photosensors each per track, generating 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, reducing the needs for external signal calibration to an absolute minimum.


• Absolute position encoders
