FIGURE 11. Settling Time and Slew Rate Test Circuit.
FIGURE 14. Composite Amplifier for Wide Bandwidth.
This composite amplifier uses the OPA603 current-feedback op amp to
provide extended bandwidth and slew rate at high closed-loop gain. The
feedback loop is closed around the composite amp, preserving the
precision input characteristics of the OPA627/637. Use separate power
supply bypass capacitors for each op amp.
