A decrease m gam can be achieved by placing matched resistors in parallel with the sense resistors, also shown in Figure 2. The adjusted gain is given by the following expression VOUT/IIN = 0.3125 x Rx/(Rx + Rs). A l% decrease m gain can be achieved with a 7.5k[ resistor. It is important to match the parallel resistance on each sense resistor to maintain high CMR. The TCR mis- match between the two extemal resistors will effect gain error drift and CMR drift.
