Koheron TIA400 is a quad-channel 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). Thanks to its multiple channels and its large input current range (up to ± 4 mA), it is well suited for system monitoring of optical powers.
The 1-channel version of Koheron TIA400 is Koheron TIA100 transimpedance amplifier.
