iC-PN2624

PHASED ARRAY NONIUS ENCODER 26-1024

Rev B1, Page 2/7

DESCRIPTION

The optical encoder iC-PN2624 features monolithi-

cally integrated photosensors arranged in a phased-

array.

A high transimpedance gain of typically 4 MΩ gener-

ates output signals of a few hundret Millivolts already

cases no additional measures must be considered to

filter for noise and interferences.

Analog nonius encoders are the typical applica-

tion for iC-PN2624.

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.

The spectral sensitivity range includes visible to near

infrared light, with the maximum sensitivity being

close to a wavelength of 680 nm. An output voltage

of approximately 1 V is typical under low light condi-

tions, for instance when iC-PN2624 is illuminated at
