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.
