This circuit converts an input current to a proportional amount of voltage. Use the two switches to select an input current. This current flows across a 1k resistor. The op-amp outputs a voltage equal to the voltage drop across the resistor in order to ensure that the – terminal is at ground, which means that the output voltage is proportional to the resistor voltage (and therefore to the input current).
