Can I de-activate the transimpdance amplifier by driving the enable pin high? What will the input impedance be for fast pulse currents (in the 10ns to 50ns range)? In other words, will the input load the detector for fast pulse currents? Will the 100mA clamp still be active? I want to divert the current to another amplifier with low gain to extend the dynamic range.
Is it possibe in the above case to still activate the DC cancellation, while I de-activate the amplifier?
Does the SPICE model support this functionality, so that I can test by simulation?
Your help will be appreciated.
