This composite amplifier uses the OPA603 current-feedback op amp toprovide extended bandwidth and slew rate at high closed-loop gain.The feedback loop is closed around the composite amp, preserving theprecision input characteristics of the OPA627/637. Use separate powersupply bypass capacitors for each op amp. See Application BulletinAB-007 for details.NOTE: (1) Minimize capacitance at this node.
