Configured INA155/156 directly driven by a capacitive input high speed A / D converter circuit as shown: A capacitive high-speed direct drive input configured as shown in FIG INA155/156 by the A / D converter in Figure G = 10. After INA155 input voltage amplification to 12 high-speed low-power sampling A / D converter ADS7818 or ADS7834. ADS7818 or ADS7834 inputs for the internal capacitor array (CDAC), is the capacitive input, analog signal conversion A / D converter input is 12-bit digital signal output, fsample = 500kHz.
