Designed using an advanced CMOS process, this part offers excellent performance, low power consumption and latch-up free operation. The XRD6414 uses a subranging architecture to maintain low power consumption at high conversion rates. Our proprietary parator 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 1.5m W (typical) by a digitally controlled pin. Providing external reference voltages allows easy interface to any input signal range between AGND and AVDD. This also allows the system to calibrate out zero scale and full scale errors by adjusting VRT and VRB. A separate power supply pin, DVDD, sets the output logic levels for 3V or 5V interface. This device operates from a single 5.0V supply. Power consumption from a 5.0V supply is typically 120m W at FS=15MHz. For 3.3V power supply operation refer to XRD64L14.
