GENERAL DESCRIPTION
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.
