iC-LQNP
PULSE AND AC LIGHT SENSOR
Rev B1, Page 2/10
DESCRIPTION
iC-LQNP is a sensor for pulse and alternating light
with a monolithically integrated photodiode. The de-
vice supersedes conventional photoreceivers, such
as those in light barriers, for example.
For visible light or near infrared the highest sensi-
tivity for alternating light signals is reached at ap-
proximately 140 kHz; for pulse light this is reached
at 1.4 µs and upwards.
Changes in the photocurrent are ampliï¬ed whereas
the photocurrents caused by background light
are electronically suppressed with over 60 dB (at
100 Hz).
The integrated ampliï¬er forms a band-pass charac-
teristic without using any external components. The
high pass ï¬lter suppresses ambient light and low fre-
quency alternating light and the low pass ï¬lter re-
duces high frequency noise.
The transimpedance can be selected within a range
of approximately 1 to 10 M⦠via the external load re-
sistor.
iC-LQNP is available as a 4-lead TO18 metal can
package with a glass lens or ï¬at window. Customised
COB versions are also possible.
