EVALUATION BOARD HARDWARE
Table 2. AD5040/AD506x Pin Configuration
Mnemonic Function
The evaluation board for the AD5040/AD506x requires a single
positive supply (+2.7 V to +5.5 V). The evaluation board for the
AD5063 requires a single negative supply, such as −5 V, for the
external on-board op amp in order to generate a bipolar signal.
A +5 VDD and −5 VLL supply are required to power the output
amplifier in the AD5063, if the user requires a bipolar signal.
The +5 V VDD is used to power the DAC. All supplies are
decoupled to ground with ±0 μF tantalum and 0.± μF ceramic
capacitors.
VDD
Power supply input. Devices can operate from 2.7 V
to 5.5 V and VDD, and should be decoupled to GND.
VREF
Reference voltage input.
DACGND
VOUT
Ground input to the DAC.
Analog output voltage from DAC.
SYNC
Level triggered control input (active low). This is
the frame synchronization signal for the input
data. When SYNC goes low, it enables the input
shift register and data is transferred in on the
falling edges of the following clocks. The DAC is
updated following the 16th clock cycle unless SYNC
is taken high before this edge in which case the
rising edge of SYNC acts as an interrupt and the
write sequence is ignored by the DAC.
EVALUATION BOARD LINK CONFIGURATON
The three link options (ꢀK±, ꢀK2, and ꢀK3) must be set before
using the evaluation board.
LK1
This sets the power to the Cypress ULB microcontroller that
controls the ULB section of the chip. The supply for the
microcontroller can be provided from an external supply or
from the computer via the ULB interface. Using the computer to
set the supply, set ꢀink ± to Position A. To use an external
supply, set the link to Position B.
SCLK
DIN
Serial clock input. Data is clocked into the input
shift register on the falling edge of the serial clock
input. Data can be transferred at rates up to 30 MHz.
Serial data input. This device has a 16-/24-bit shift
register. Data is clocked into the register on the
falling edge of the serial clock input.
AGND
INV1
Ground reference point for analog circuitry on part.
Connected to the internal scaling resistors of the
DAC. Connect the INV pin to the external op amp’s
inverting input in bipolar mode.
Feedback resistor. In bipolar mode, connect this
pin to the external op amp circuit.
LK2
ꢀink 2 connects the on chip reference to the Reference pin on
the DAC. If you are using the ADR423 to provide the reference
to the DAC, then ꢀink 2 must be set.

The AD5040/AD5060/AD506±/AD5062 have 8 pins while the
AD5063 has ±0 pins as described in Table 2. Note that the last
two entries in Table 2 (Pin INV and Pin RFB) apply only to the
AD5063. Communication to the devices is accomplished via the
Cypress CY7C630±3 microcontroller Pin 45, Pin 46, and Pin 47.

EVALUATION BOARD SOFTWARE
3. Lelect how the device should operate. Choose Normal to
operate the device in normal mode. For power-down
mode, choose one of the three available options
(Tri-State, 100 kOhm to GND or 1 kOhm to GND) as
shown in Figure 3.
INSTALLING THE SOFTWARE
The AD5040/AD506x evaluation kit includes self-installing
software on CD-ROM. The software is compatible with
Microsoft® Windows® 95 or higher.
Install the evaluation board software before connecting the
evaluation board to the ULB port of the PC. This ensures the
evaluation board is correctly recognized when connected to the PC.
4. Enter the DAC code in either decimal or hex code. Lelect
the field populated with zeroes (0000) for decimal or Hex
for hex. The AD5040 accepts a ±6-bit command whereas
AD506x accepts a 24-bit command.
±. Ltart the Windows operating system and insert the CD-ROM.
The installation software launches automatically. If it does
not, use Windows Explorer to locate the file setup.exe on
the CD-ROM. Lelect this file to start the installation
procedure.
5. Lelect Update DAC to update DAC output.
2. At the prompt, select a destination directory, which is
C:\Program Files\Analog Devices\AD506X by default.
Once the directory is selected, the installation procedure
copies the files into the relevant directories on the hard
drive. The installation program creates a program group
called Analog Devices with subgroup AD506X in the
Start menu of the taskbar.
OPERATING THE SOFTWARE
±. Once the installation procedure is complete, select the
AD5040/60/61/62/63 icon to start the program.
2. Choose the part to be tested as shown in Figure 2.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
