Description : PULSE AND AC LIGHT SENSOR

DESCRIPTION
iC-LQNP is a sensor for pulse and alternating light with a monolithically integrated photodiode. The device supersedes conventional photoreceivers, such as those in light barriers, for example.
Changes in the photocurrent are amplified whereas the photocurrents caused by background light are electronically suppressed with over 60 dB (at 100 Hz).

FEATURES
♦ Fast response amplifier with on-chip photodiode
♦ High interference immunity due to monolithic design
♦ Active photodiode area of ca. 1 mm²
♦ 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
♦ 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

APPLICATIONS
♦ 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.
