Our proprietary comparator design achieves a low analog input capacitance. The input circuitry of the XRD6414 includes an on-chip S/H function that allows the product to digitize analog input signals between AGND and AVDD. The XRD6414 can be placed into power down (stand-by) mode, reducing the power dissipation to 1.5mW (typical) by a digitally controlled pin.
