The AD549 is a monolithic electrometer operational amplifier with very low input bias current. Input offset voltage and input offset voltage drift are laser trimmed for precision performance. The ultralow input current of the part is achieved with TopgateTM JFET technology, a process development.
Optical receivers with amplifiers are used to amplify the weak electrical signal generated by the photodetector. An illustration of the effective gainis given below. Note the presence of a gain peak around 1530nm and a semi-flat gain. Our optical receivers and detectors make photodetection easy and provide the lowest noise and cleanest response possible.

An optical amplifieris a device that amplifies an optical signal without first converting it into an electric signal. Optical signals, such as lasers, can be improved in their strength or power through the u.
