Tool/software:
Hi,
Can we increase the input current limit for the TIA by reducing the gain of the chip?
OPA857 has a selectable gain using CTRL pin. I've it at 5k gain at the moment which has a current limit of 240uA. If I want to increase that limit to around 1mA, can I add an external resistor or a parallel capacitor across IN and OUT pin to reduce the gain to increase the current input limit? Does this chip support that feature?
Please let me know, thanks
