I recently purchased from a US supplier InGaAs photodiodes PINTIA with built-in transimpedance pre amp(150MH bandwidth). The supplier spec sheet says if I supply 5V across 2 specified leads I will get about 3.V output on the other 2 leads(inverting and non-inverting) after I attach 1mW 1550nm laser diode to the PIN TIA. But I am not measuring anything.
What may have gone wrong? I took care in soldering time and ESD.
How do I check if the diode is damaged? Do I need to do anything further such as attching a load resistor?
