OP297
OPEN-LOOP GAIN LINEARITY
The OP297 has both an extremely high gain of 2000 V/mV
minimum and constant gain linearity. This enhances the
precision of the OP297 and provides for very high accuracy in
high closed-loop gain applications. Figure 30 illustrates the
typical open-loop gain linearity of the OP297 over the military
temperature range.
