iC-LQNP
PULSE AND AC LIGHT SENSOR
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 infra-red
• 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 analog current source outputs, transimpedance
can be set by external resistor
• Single 5 to 12 V supply, low power consumption also with bright
ambient light

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.
