GENERAL PURPOSE SILICON DETECTOR/PREAMPLIFIER
These detector/preamp hybrids combine planar diffused photodiode chips with monolithic op-amps in the transimpedance
amplifier configuration. The feedback capacitor and resistor are connected externally by the user, allowing customization of the
feedback circuit. The op-amps utilize JFET inputs for low input offset currents, and exhibit gain bandwidth products of 28MHz. The
user can also choose between red, blue or UV enhanced spectral response, and between active photodetector areas of 100mm
2
and 5.1mm
2
. As an option, volume users can specify internally mounted resistors and capacitors.
