EVALUATION BOARD
An evaluation board which is available for the AD9032 (part
number AD9034/PCB) provides an easy and flexible method
for evaluating the ADC’s performance without (or prior to)
developing a user-specified printed circuit board. The evalua-
tion board was originally designed and used for evaluating the
AD9034 A/D converter, but is equally useful for the pin-
compatible AD9032.
The board includes a reconstruction DAC, analog input ampli-
fier, and digital output interface. Physically, it is 7.25 inches
3
6 inches in size and uses the layout and applications information
contained in the AD9034 data sheet.
Generous space is provided near the analog input and digital
outputs of the evaluation board to support additional signal pro-
cessing components the user may wish to add. These two proto-
typing areas include through holes with 100-mil centers to
support a variety of component additions.
For additional operating details, a schematic of the evaluation
board, and complete layout information, consult the data sheet
on the AD9034 A/D converter.
GENERAL DESCRIPTION
The AD9032 is the world’s fastest 12-bit analog-to-digital con-
verter (ADC) that includes on-board T/H, voltage references,
and timing circuits. The AD9032 uses a subranging converter
architecture to achieve sample rates from dc to 25.6 MSPS. Pack-
aged in a single 40-pin hybrid, the AD9032 is pin-compatible with
the AD9034, which operates at word rates up to 20 MSPS.
This ECL-compatible ADC requires only +5 V and –5.2 V sup-
plies, an analog input, and a stable ECL clock to obtain the best
dynamic performance available in a 12-bit ADC. This kind of
performance is achieved with advanced bipolar circuits, custom
designed and manufactured by Analog Devices. The latest in
monolithic track-and-hold technology ensures accurate sam-
pling of high frequency analog inputs.
Dynamic performance has been optimized to achieve SNR of
64 dB and a spurious-free dynamic range (SFDR) of 74 dB for
analog bandwidths up to 12 MHz. All units are tested for dy-
namic performance at a sample rate of 25.6 MSPS.
The AD9032 is available in either a 40-pin ceramic DIP or
leaded flatpack. The two versions operate over an industrial
(–25
°
C to +85
°
C) or military (–55
°
C to +125
°
C) temperature
range.
