Figure 27 shows the expected results for the Noninverting Operation of the OPA548. The left picture shows the Noninverting Operation in dual supply mode and the right picture shows the Noninverting Operation in single supply mode. The input signal is a zero-centered sine wave with an amplitude of 10 V p-p and a frequency of 1 kHz. In this trace the OPA548 is delivering a peak current of 1.25 A to the 4-Ω load.
