INA321/322 constituted by a direct drive capacitive input A / D converter circuit as shown: As shown directly driving a capacitive input constituted by INA321/322 A / D converter. Since INA321/322 output is a low, so you can work at high frequencies directly drive capacitive loads. After INA321/322 amplified input voltage output, directly to the 12 high-speed low-power sampling A / D converter ADS7818 or ADS7822. ADS7818 or ADS7822 internal input terminal of the capacitor array (CDAC) digital-analog conversion, is a capacitive input, converts the analog signal A / D converter 12 converts the input digital signal output.
