Home / Operational Amplifier Transimpedance
In electronics, a transimpedance amplifier (TIA) is a current to voltage converter, almost exclusively implemented with one or more operational amplifiers (opamps). It's also a common building block that helps explain the performance and stability limits of many other op-amp circuits. TIAs present a low-impedance input for current-output sensors such as photodiodes, preserving linear conversion and bandwidth. At its simplest, it's an operational amplifier with a feedback resistor, and the output voltage follows Ohm's law: V_out = I × R_F, where I is the input current and R_F is the feedback.
