PRODUCTION DATA
The OPAx30x series op amps use a classic two-stage topology, shown in Figure 6-1. The differential input pair is biased to maximize slew rate without compromising stability or bandwidth. The folded cascode adds the signal from the input pair and presents a differential signal to the class AB output stage. The class AB output stage allows rail- to-rail output swing, with high-impedance loads (> 2kΩ), typically 100mV from the supply rails. With 10Ω loads, a useful output swing is achieved and still maintains high open-loop gain. See the typical characteristic Figure 5-19
