Home / Transimpedance amplifiers can be used for DC
In electronics, a transimpedance amplifier (TIA) is a current to voltage converter, almost exclusively implemented with one or more operational amplifiers (opamps). The TIA can be used to amplify the current output of Geiger–Müller tubes, photo multiplier tubes, accelerometers, photodetectors and other sensors (that are modeled well as a current source) into a usable voltage.

There are a number of MC head amp designs out there, and proponents thereof, with common-base input stages or an op-amp effectively wired as a transimpedance amplifier with the
If the signal source (e.g. a photodetector) requires a DC path to ground, an internal bias tee or DC-return can be used. So, all our amplifiers work well with AC input
Although all operational amplifiers can be used in transimpedance applications, the limit in performance is always limited by the transimpedance gain, the bandwidth, and the noise.
