The G8195-12 photodiode was used with a fixed reverse bias voltage of 5V. The cathode was connected to the VS+ 5V supply, and the anode to the I1 pin. GND is used for the VCM potential. The IBIAS feature and REF165 voltage reference were not needed; therefore, the IBIAS and REF165 pins are left floating. The auxiliary amplifier was not needed; therefore, the auxiliary amplifier was placed in a buffer configuration and used to buffer the REF25 reference voltage.
GND was used for the REFA input of the logarithmic difference amplifier. The circuit output follows the expression
such that the expected output for a 100nA input is –500mV, the expected output for a 10μA input is 250mV, and so on.
