The VMID(OUT) pin of the INA165x is stable with capacitive loads up to 150 pF. An isolation resistor (RISO in Figure 49), must be used if capacitive loads larger than 150 pF are connected to the VMID(OUT) pin. Figure 49 shows the recommended configuration of an isolation resistor in series with the capacitive load. The REF pins of the INA1650 must connect directly to the VMID(OUT) pin before the isolation resistor. Any resistance placed between the VMID(OUT) pin and the reference pins degrades the CMRR of the device. Figure 50 shows the recommended value for the isolation resistor for increasing capacitive loads.
