Transimpedance amplifier
Koheron TIA100 is the 1-channel version of Koheron TIA400 quad-channel transimpedance amplifier. It is a transimpedance amplifier (TIA) with a bandwidth of 2 MHz and an input-referred current noise of 5 pA/√Hz. It is compatible with photodiodes with up to 200 pF input capacitance (including cable capacitance).
