SERIAL INTERFACE

The EVAL-AD4111SDZ connects via the serial peripheral
interface (SPI) to the Blackfin®
board. There are four primary signals: CS , SCLK, DIN (all
inputs), and DOUT/ RDY (output from the ADC).
The EVAL-AD4111SDZ can be connected to the
ADuCM3029 EZ-KIT
evaluation board to the
user to develop their own C code rather than using the provided
evaluation software.
To operate the EVAL-AD4111SDZ in standalone mode,
disconnect any board connected to J8 and use J10 to access all
SPI signals and set the input/output voltage levels.

POWER SUPPLIES

By default, the board is powered from the
The board can be also powered from J6 and J7 (set LK3 to
Position A) or from Pin +5V on J10 (see Table 2).
The ADuM5411 isoPower® digital isolator is used to isolate
power and data lines up to 2.5 kV rms.

ANALOG INPUTS

There are two types of analog inputs: voltage and current.
Eight voltage inputs are available on J1 and J2. Four current
inputs are available on J3.
If a different common voltage must be set for single-ended
measurement, remove LK2 and connect the desired voltage to
VCOM on J1.

REFERENCE OPTIONS

The EVAL-AD4111SDZ includes an external 2.5 V reference,
the ADR4525ARZ. By default, LK1 is inserted, connecting the
external reference to the REF+ pin of the AD4111.
Remove LK1 if using a different single-ended external reference.
In the evaluation software, click the blue pop-up button
associated with Setup 0 to Setup 7 to select the reference used
for conversions by the AD4111. The pop-up button is located
below the external reference controls in the block diagram
(Label 9 in Figure 16).
