GENERAL DESCRIPTION
The XRD6406 is a 10-bit, 6 MSPS, Analog-to-Digital
Converter 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.
TheXRD6406uses asubrangingarchitecturetomaintain
low power consumption at high conversion rates. Our
proprietary comparator design achieves a low analog
input capacitance. The input circuitry of the XRD6406
includes an on-chip S/H function that allows this part to
digitize analog input signals between AGND and AV
DD
.
The designer can choose the internally generated
reference
voltages,
or provide
voltages totheV
RB
andV
RT
pins. Theinternalreference
generates 1.0V atV
RB
and4V atV
RT
. Providing external
reference voltages allows easy interface to any input
signalrange betweenGND andV
DD
. This alsoallows the
system to cancel zero scale and full scale errors. The
Reference Ladder taps (R1 to R3) can be used to
externally trim any INL errors.

This device operates from a single 5V supply. Power
consumption from a 5V supply is typically 65mW at
