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 AV
DD
.
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
AV
DD
. This also allows the system to calibrate out zero
scale and full scale errors by adjusting V
RT
and V
RB
. A
separate power supply pin, DV
DD,
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
F
S
=15MHz. For 3.3V power supply operation refer to
XRD64L14.
