HARDWARE SETUP

This section details how to set up the AD4050/AD4052 and SDP-K1
boards for use with the AD4050/AD4052 ACE plugin. Refer to
the Evaluation Board Hardware
of the on-board circuit blocks and for descriptions of all jumpers
referenced in this section.
To set up the hardware, complete the following steps:
Disconnect both the evaluation board and the SDP-K1 from all
►
power sources before connecting them together.
The EVAL-AD4050-ARDZ/EVAL-AD4052-ARDZ connect to the
►
SDP-K1 via the Arduino Uno compatible headers (P1 to P4).
Plug the headers on the bottom side of the evaluation board to
the corresponding headers on the top side of the SDP-K1 (see
Figure 2).
Figure 2. EVAL-AD4052-ARDZ and SDP-K1 Connections
The SDP-K1 supports both 3.3 V and 1.8 V logic levels, and the
logic level is selected with the VIO_ADJUST jumper. Although the
AD4050/AD4052 ADCs are compatible with either logic level, the
AD4050/AD4052 ACE plugin requires that VIO_ADJUST be set to
3.3 V.

After the EVAL-AD4050-ARDZ/EVAL-AD4052-ARDZ are connected
to the SDP-K1 board and the VIO_ADJUST jumper is in the de-
sired location, power can be applied to the SDP-K1. The SDP-K1
accepts power from either the USB cable and port from the PC
or from a separate switched-mode DC power supply (7 V to 12 V,
see the SDP-K1 User Guide for more information). The DS1 light-
emitting diode (LED) illuminates when the EVAL-AD4050-ARDZ/
EVAL-AD4052-ARDZ are receiving power from the SDP-K1 and is
generating the +3.3 V rail to the on-board AD4050/AD4052 and its
companion circuitry.
When powering from the USB, perform the following steps:
Ensure the JP2 jumper on the EVAL-AD4050-ARDZ/EVAL-
►
AD4052-ARDZ is set to the +5 V position. This position connects
the evaluation board power management circuitry to the +5 V pin
on the Arduino Uno power header.
Connect the SDP-K1 to the PC with a USB cable. After a few
►
seconds, the SYS_PWR LED on the SDP-K1 illuminates to
indicate the SDP-K1 is receiving power from the USB.

When powering from an external power supply, perform the follow-
ing steps:
Ensure the JP2 jumper on the EVAL-AD4050-ARDZ/EVAL-
►
AD4052-ARDZ is set to the VIN position. This position connects
the evaluation board power management circuitry to the VIN pin
on the Arduino Uno power header.
Plug the external power supply into the DC jack (P15) on the
►
SDP-K1. The SYS_PWR LED on the SDP-K1 illuminates to
indicate the SDP-K1 is receiving power from the external power
supply.
After the external power supply is connected, connect the SDP-
►
K1 to the PC with a USB cable.
