 Figure 2: 

Figure 2 shows a suggested simple test circuit that you can build to gain a familiarity with the evaluation

kit as well as the amplifier. At the A OUT or B OUT pads relative to power ground you should observe a square
wave with a frequency of approximately 500kHz, 30V p-p which is being modulated from approximately 0 to
100% duty cycle at a rate of 1 Hz.
