About Transimpedance Amplifiers
Analog Devices Transimpedance Amplifiers
A transimpedance amplifier, also known as a current-to-voltage converter, is an electronic circuit that converts an input current into an output voltage. It is an amplifier used in the field of electronics to convert current signals into a voltage signal. A transimpedance amplifier is an inverting amplifier, meaning that the output voltage is proportional to the negative of the input current. It is typically used for applications where there are large currents supplied from photodiodes, photomultipliers, Hall-effect sensors, and other such electrical transducers–where the small current signals generated by them need to be read by an external device with a high input impedance.
