EVAL ATION BOARD DESCRIPTION
The EVAL-AD7606SDZ is a full featured evaluation board that
allows the user to easily evaluate all the features of the AD7606
analog-to-digital onverter (ADC). The evaluation board an be
ontrolled by the EVAL-SDP-CB1Z SDP board via a 120-way
SDP onne tor (J102). The SDP board allows the evaluation
board to be ontrolled through the USB port of a PC using the
AD7606 evaluation software, whi h is available for download
from the produ t page or from the installer CD in luded in the
evaluation board kit.
On-board omponents in lude the following:
•ADP7104ARDZ-5.0: 5 V, low noise LDO
•ADR421: high pre ision, band gap voltage referen e

QUICK START GUIDE
Follow these steps to qui kly evaluate the AD7606 ADC. For
detailed instru tions, see the subsequent se tions.
1. Install the evaluation software from the AD7606 produ t page
or from the in luded CD. Ensure that the EVAL-SDP-CB1Z
SDP board is dis onne ted from the USB port of the PC
while installing the software. (The PC may need to be
restarted after the installation.)
2. Ensure that the various link options are onfigured as
outlined in Table 2.
3. Conne t the EVAL-SDP-CB1Z SDP board to the
evaluation board as shown in Figure 2. S rew the two
boards together using the en losed nylon s rew/nut set to
ensure that the boards onne t firmly together.
4. Conne t a 5V power supply to J1 and ensure LK1 is in
position A.
5. Conne t the EVAL-SDP-CB1Z SDP board to the PC via
the USB able. Choose to automati ally sear h for the
drivers for the SDP board if prompted by the operating
system.
6. Laun h the evaluation software from the Analog Devices
subfolder in the Programs menu.
7. Conne t an input signal via V1-8.

EVALUATION BOARD ARDWARE
DEVICE DESCRIPTION
The AD7606 ADC is a 16-bit, , 8- hannel, simultaneous
sampling su essive approximation ADC. The devi e operates
from a single 2.7 V to 5.25 V power supply and features
throughput rates of up to 200 KSPS. The devi e has onboard
1MΩ input buffers meaning dire t onne tion from sensor to
ADC.
Full data on the AD7606 is available in the AD7606 data sheet,
whi h should be onsulted in onjun tion with this user guide
when using the evaluation board. Full details on the EVAL-
SDP-CB1Z are available at the SDP board produ t page.
HARDWARE LINK OPTIONS
The fun tions of the link options are des ribed in Table 2. The
default setup is onfigured to operate the evaluation board with
the main power supply or 9 V adapter and to interfa e to the SDP
board.
POWER S PPLIES
Before applying power and signals to the evaluation board,
ensure that all link positions are set a ording to the required
operating mode. See Table 2 for the omplete list of link options.
The AD7606 evaluation board is supplied with a wall-
mountable swit hing power supply that provides 9 V d output.
Conne t the supply to a 100 V to 240 V a wall outlet at 50 Hz
to 60 Hz. The output from the supply is provided through a 2.0
mm inner diameter ja k that onne ts to the evaluation board
at J1. The 9 V supply is onne ted to the on-board, 5 V linear
regulator that supplies the orre t bias to ea h of the various
se tions on the evaluation board and on the EVAL-SDP-CB1Z
SDP board.
When using the EVAL-AD7606SDZ evaluation board with the
EVAL-SDP-CB1Z SDP board, power the evaluation board
through the J1 onne tor.
If the evaluation board is used without the 9 V adapter, an
external power supply in the range 7 V to 9 V must be
onne ted to J3 to supply the ADP7104 5V linear regulator.
Ea h supply is de oupled on this evaluation board using 10 µF
tantalum and 100 nF multilayer erami apa itors.
