SERIAL INTERFACE

The EVAL-AD4115SDZ connects via the SPI to either the
connector or Arduino header. There are four primary signals,
three inputs ( CS , SCLK, and DIN), and one output from the
ADC (DOUT/ RDY ).
The EVAL-AD4115SDZ connects to any microcontroller board
that uses the Arduino standard headers. The Arduino standard
headers allow the user to develop code for a variety of platforms.
To operate the EVAL-AD4115SDZ in standalone mode,
disconnect any SDP board connected, remove the jumpers in
the J6 header, and use the middle row of pins on J6 to access all
SPI signals and set the input/output voltage levels.

POWER SUPPLIES

By default, the EVAL-AD4115SDZ is powered from the USB.
The EVAL-AD4115SDZ can also be powered from the J4
connector by setting LK3 to Position A, or from Pin +5V on
Connector J6 (see Table 2).

ANALOG INPUTS

Sixteen voltage inputs are available on J2 and J3. If a different
common voltage must be set for single-ended measurement,
remove LK2 and connect the desired voltage to VINCOM on J3.

REFERENCE OPTIONS

The EVAL-AD4115SDZ includes an external 2.5 V reference,
the ADR4525ARZ. By default, LK1 is inserted, connecting the
external reference to the REF+ pin of the AD4115. Remove LK1
if using a different single-ended external reference.
