U6791B-C

The U6791B-C has the following features including 220 MHz bandwidth over temperature and supply voltage range;Wide 60 dB input dynamic range;Low-power design: 20 mA maximum;Low-noise design;Temperature compensated;Available in S08 package or chip form.

U6791B-C is a low-noise, wideband IC designed formamplifying low-level current signals delivered by PIN photo diodes in fiberoptic receiver systems. It contains a transimpedance amplifier and a voltage regulator that provides a supply independent voltage with a positive temperature coefficient to hold bandwidth constant over temperature. For best performance, an additional pin, VPD, is used to filter the supply voltage for the photo diode. The circuit provides quasi-complementary outputs and works best ac coupled to U6792B-D.To maintain a constant bandwidth over supply voltage and temperature variations, VREG is provided and should be decoupled by an external capacitor. For best results it is recommended to use the U6791B-C ac coupled to the U6792B-D data quantizer, because these two IC's are well matched for amplification and signal monitoring.

The U6791B-C is described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but U6791B-C is not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
