OSI Optoelectronics Photodiode Preamp (Photop™) UDT-555D

The Photop™ Series, combines a photodiode with an operational amplifier in the same package. Photop general-purpose detectors have a spectral range from either 350 nm to 1100 nm or 200 nm to 1100 nm. They have an integrated package ensuring low noise output under a variety of operating conditions. These op-amps are specifically selected by OSI Optoelectronics engineers for compatibility to our photodiodes. Among many of these specific parameters are low noise. Low drift and capability of supporting a variety of gains and bandwidths determined by the external feedback components. Operation from DC level to several MHz is possible in an either unbiased configuration for low speed, low drift applications or biased for faster response time. LN-Series Photop„¢ are to be used with OV-bias. Any modification of the above devices is possible. The modifications can be simply adding a bandpass optical filter, integration of additional chip (hybrid) components inside the same package, utilizing a different op-amp, photodetector replacement, modified package design and / or mount on PCB or ceramic.
