This degrades common-mode rejection. The differential input capacitor, C3, reduces the bandwidth and mitigates the effects of mismatch in C1 and C2. Make C3 much larger than C1 and C2. If properly matched, C1 and C2 also improve CMR. OUTPUT VOLTAGE SENSE (SOL-16 Package Only) The surface-mount version of the INA111 has a separate output sense feedback connection (pin 12). Pin 12 must be connected, usually to the output terminal, pin 11, for proper operation. (This connection is made internally on the DIP version of the INA111.) The output feedback connection can be used to sense the output voltage directly at the load for best accuracy. Figure 8 shows how to drive a load through series interconnection resistance. Remotely located feedback paths may cause instability. This can be generally be eliminated with a high frequency feedback path through C1. FIGURE 6. Input Low-Pass Filter. FIGURE 8.
