iC-LQNP Pulse and AC Light Sensor with Complementary Outputs

Applications	Amplification of pulse and AC light signals 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.

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 Fast recovery from flashes Complementary analogue current source/sink 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
