MACOM's transimpedance amplifiers (TIAs) deliver the perfect combination of high performance at with low power and low cost. Most devices in the family have an automatic gain control (AGC) for improved dynamic range and a photocurrent monitor indicator. Transimpedance Amplifiers (TIAs) work in GPON optical-network-terminals (ONTs). It also may be used for SONET, CPRI base station, and SFF/SFP optical transceiver applications/modules.

Transimpedance Amplifiers (TIAs)

An important case is when you need an op-amp to amplify the signal from a sensor, such as a photodiode. (Photodiodes put out the current at high impedance. Often they have a "big" capacity.) If the photo diode dump the current-out into a input resistor, there are two problems: is the resistor large, then the gain can be fairly large and the response time will be slow (the time-constant will be large); a small resistor get a small t and a low gain.

 

It's a good idea to connect the photodiode's output directly to a transimpedance amplifier (TIA), it's also sometimes referred to as a "current-to-voltage converter". MACOM's optoelectronics products includes a wide range of transimpedance amplifiers (TIA) for line and client side with 10G, 40G and 100G fiber-optic- receivers. There are linear TIAs for long haul coherent receivers and limiting TIAs for shorter range NRZ based receivers available. They are available in "die-form" for integration with photo-detectors in an optical sub-assembly.
