Due the INA321/322 output is in low in resistance, the high-frequency work can directly drive capacitive loads. Input voltage is amplified and output by INA321/322, then it is sent to the 12 - bit high - speed low-power sampling A / D converter ADS7818 or ADS7822. ADS7818 or ADS7822 internal input terminal is the capacitor array (CDAC) digital-analog converter, that is a capacitive input, A / D converter converts the input analog signal to 12-bit digital signal output.
