GENERAL DESCRIPTION
The XRD8785 is an 8-bit Analog-to-Digital Converter.
Designed using an advanced 5V 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 XRD8785 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 XRD8785. The designer can choose the internally
generated reference voltages by connecting V
RB to
20-Pin Package Available: XRD8775
3V Version: XRD87L85
APPLICATIONS
Digital Color Copiers
Cellular Telephones
CCDs and Scanners
Video Capture Boards
V
RBS and VRT to VRTS, or provide external reference
voltages to the V
RB and VRT pins. The internal reference
generates 0.6V at V
RB and 2.6 V at VRT. 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 +5V supply. Power
consumption is 75mW at FS = 15MHz. Specified for
operation over the commercial/industrial (–40 to
+85°C) temperature range, the XRD8785 is available in
Plastic Dual-in-line (PDIP), Surface Mount (SOIC) and
Small Outline (SOP) packages in EIAJ and JEDEC.
