The OP2 8 4 is a low noise dual op amp with 4MHz bandwidth and true rail-to-input input and output operation. These features make it ideal for low supply voltages, as used in the 2 op amp measurement amplifiers shown in this figure. The circuit uses two conventional op amps to measure the topology and four resistors to set the gain. Turn of the circuit
