Shield is driven at the

current limit behavior. The inputs are protected even if no
power supply voltage is present.
OUTPUT VOLTAGE SENSE (SOL-16 package only)
The surface-mount version of the INA114 has a separate
output sense feedback connection (pin 12). Pin 12 must be
connected to the output terminal (pin 11) for proper opera-
tion. (This connection is made internally on the DIP version
of the INA114.)
The output sense connection can be used to sense the output
voltage directly at the load for best accuracy. Figure 5 shows
how to drive a load through series interconnection resis-
tance. Remotely located feedback paths may cause instabil-
ity. This can be generally be eliminated with a high
frequency feedback path through C
1
. Heavy loads or long
lines can be driven by connecting a buffer inside the feed-
back path (Figure 6).
