FEATURES
APPLICATIONS
♦ Fast response amplifier with on-chip photodiode
♦ High interference immunity due to monolithic design
♦ Active photodiode area of ca. 1 mm²
♦ Receiver for through beam and
reflection light barriers with
background suppression
(sunlight) e.g. for presence
detection in power operated
gates, doors and windows etc.
♦ Suitable for visible light and near infrared
♦ Integrated band-pass filter with 140 kHz center frequency
♦ Maximum gain obtained for pulse light of 1.4 µs and upwards
♦ High LF and DC (ambient) light suppression
♦ Transfer characteristics irrespective of ambient light level
♦ Soft signal and noise limiter with excess ambient light
♦ Fast recovery from flashes
PACKAGES
♦ Complementary analogue current source outputs,
transimpedance can be set by external resistor
♦ Single 5 to 12 V supply, low power consumption also with
bright ambient light
♦ Options: customised COB versions

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