GENERAL DESCRIPTION
The XRD87L85 is an 8-bit Analog-to-Digital Converter.
Designed using an advanced 3.3V CMOS process,
this part offers excellent performance, low power con-
sumption, and latch-up free operation.
This device uses a two-step flash architecture to
maintain low power consumption at high conversion
rates. The input circuitry of the XRD87L85 includes an
on-chip S/H function which allows the user to digitize
analog input signals between AGND and AV
DD
. Careful
design and chip layout have achieved a low analog
input capacitance. This reduces “kickback” and eases
the requirements of the buffer/amplifier used to drive
the XRD87L85. The designer can choose the internally
generated reference voltages by connecting V
RB
to
Latch-Up Free
ESD Protection: 2000V Minimum
20-Pin Package Available: XRD87L75
APPLICATIONS
Digital Color Copiers
Cellular Telephones
CCDs and Scanners
Video Capture Boards
V
RBS
and V
RT
to V
RTS
, or provide external reference
voltages to the V
RB
and V
RT
pins. The internal reference
generates 0.4V at V
RB
and 1.72V at V
RT
. Providing
external reference voltages allows easy interface to
any input signal range between AGND and AV
DD
. This
also allows the system to adjust these voltages to
cancel zero scale and full scale errors, or to change the
input range as needed.
The device operates from a single +3.3V supply.
Power consumption is 25mW at FS = 6MHz. Specified
for operation over the commercial/industrial (–40 to
+85°C) temperature range, the XRD87L85 is available
in Plastic Dual-in-line (PDIP), Surface Mount (SOIC)
and Small Outline (SOP) packages in EIAJ and
JEDEC.
