Figure 25. Open-Loop Gain Linearity
Actual open-loop voltage gain can vary greatly at various output
voltages. All automated testers use endpoint testing and therefore
only show the average gain. This causes errors in high closed-
loop gain circuits. Because this is difficult for manufacturers to
test, users should make their own evaluations. This simple test
circuit makes it easy. An ideal op amp would show a horizontal
scope trace.

Figure 26. Output Gain Linearity Trace
This is the output gain linearity trace for the new OP77. The
output trace is virtually horizontal at all points, assuring
extremely high gain accuracy. The average open-loop gain is
truly impressive—approximately 10,000,000.
