NOTES:
1 Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation at or above this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.
2 Any input pin which can see a value outside the absolute maximum ratings should be protected by Schottky diode clamps (HP5082-2835) from input pin to the supplies. All inputs have protection diodes which will protect the device from shorttransients outside the supplies of less than 100mA for less than 100ms.
3 VDD refers to AVDD and DVDD. GND refers to AGND and DGND.

The XRD6414 is a 10-bit, 20 MSPS, Analog-to-Digital Converter (ADC) with a 4:1 Analog Input Multiplexer for applications that require high speed and high accuracy. 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 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. 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 120mW at FS=15MHz. For 3.3V power supply operation refer to XRD64L14.
