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
from illumination levels of 1 to 3 mW/cm². In most
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
only 1.5 mW/cm² by an 740 nm LED.
