LMH6612MA Datasheet, PDF (26/32 Pages) Texas Instruments – Single Supply 345 MHz Rail-to-Rail Output Amplifiers

The following table summarizes the performance of the
LMH6612 combined with the ADC121S625 at two different
frequencies. In order to utilize the full dynamic range of the
ADC, the maximum input of 2.5 V_PP is applied to the ADC
input. Figure 8 shows the FFT plot of the LMH6612 and AD-
C121S625 combination tested at f = 20 kHz input frequency.
