current gain of an op amp?
need to convert current(output of a detector) in the range of pico amps to voltage between 1-5V
(to connect to an adc)
I've connected an op amp(for current amplification) to a resistor(to convert the amplified current into voltage)and grounded it and a friend suggested using TL071 op amp.but i don't know much about op amps.
what i want to know is for a certain input current and for a certain op amp how can i calculate the output current?
only by knowing that i can calculate the value of the resistor to be used
the data sheet gives voltage gain but not current gain.
please help me out
