Sample and hold amplifier AD9101 interface circuit

As shown in the figure, this is the interface circuit of AD9101 for fast (Flash) sampling. When the signal frequency increases, the traditional fast sampling circuit has to sacrifice the dynamic range in exchange for the stability of the overall performance. The circuit in the figure uses AD9101 and high-speed 8-bit A/D converter AD9002 to improve the high-frequency performance of Flash ADC; at the same time, the voltage regulator and op amp voltage follower output are used to raise the RTN pin potential of AD9101 to 0.33V.
