The picture shows the single operational amplifier basic subtraction circuit. To avoid the error caused by the bias current, it is required that the external circuit total resistance value of the operational amplifier's two input ports should be balanced. This circuit uses the element of LM158. It is a single-chip high-gain dual operational amplifiers which would work under a wide range of single power supply. Its power current would be small and would have no relations to the power voltage. The LM158's main parameters are listed in the table.
