�9 Photops™ Photodiode-Amplifier Hybrids n FEATURES • Detector/Amplifier Combined • Adjustable Gain/Bandwidth • Low Noise • Wide Bandwidth • DIP Package • Large Active Area n APPLICATIONS • General Purpose Light Detection • Laser Power Monitoring • Medical Analysis • Laser Communications • Bar Code Readers • Industrial Control Sensors • Pollution Monitoring • Guidance Systems • Colorimeter The Photop™ Series, combines a photodiode with an operational amplifier in the same package. Photops™ general-purpose detectors have a spectral range from either �50 nm to 1100 nm or �00 nm to 1100nm. 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 Photops™ 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.

UDT-020D, 020UV UDT-451, 455LN, 455UV/LN UDT-555UV/LN Photop Series Schematic Diagrams The output voltage is proportional to the light intensity of the light and is given by: (1) Frequency Response (Photodiode/Amplifier Combination) The frequency response of the photodiode / amplifier combination is determined by the characteristics of the photodetector, pre-amplifier as well as the feedback resistor (RF) and feedback capacitor (CF). For a known gain, (RF), the �dB frequency response of the detector/pre-amp combination is given by: (2) However, the desired frequency response is limited by the Gain Bandwidth Product (GBP) of the op-amp. In order to have a stable output, the values of the RF and CF must be chosen such that the �dB frequency response of the detector / pre-amp combination, be less than the maximum frequency of the op-amp, i.e. f�dB ≤ fmax. (3) where CA is the amplifier input capacitance. In conclusion, an example for frequency response calculations, is given below. For a gain of 108, an operating frequency of 100 Hz, and an op- amp with GBP of 5 MHz: (4) Thus, for CF = 15.9 pF, CJ = 15 pF and CA = 7 pF, fmax is about 14.5 kHz. Hence, the circuit is stable since f�dB ≤ fmax. For more detailed application specific discussions and further reading, refer to the APPLICATION NOTES INDEX in the catalog.
