Product Information

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). The integrated amplifier forms a band-pass characteristic without using any external components. The high pass filter suppresses ambient light and low frequency alternating light and the low pass filter reduces high frequency noise. For visible light or near infrared the highest sensitivity for alternating light signals is reached at approximately 140 kHz; for pulse light this is reached at 1.4 µs and upwards. The transimpedance can be selected within a range of approximately 1 to 10M via the external load resistor. iC-LQNP is available as a 4-lead TO18 metal can package with a glass lens or flat window. Customised COB versions are also possible.
