Please select your scenario
- I just want to see the AD5677R driver code.
SDP-K1 and AD5677R evaluation board
Hardware setup
- Connect the EVAL-AD5677R to the SDP-K1 controller board.
- Connect the SDP-K1 controller board to your computer over USB.
Software setup
The software stack is structured in the following way:
- Go to the link of the code provided above in the 'Downloads' section and import code into Mbed online compiler (Edit app_config.h file (defaults to SDP connector and AD5686R device) if evaluating any other device).
- Ensure SDP-K1 controller board is selected (top right of online-compiler page).
- Compile the code.
- After a successful compile a binary will be downloaded to your computer - store this on your drive.
- Drag and drop this binary to the USB drive hosted by your controller board.
- Start up a serial terminal emulator (e.g. Tera Term)
- Find the com-port your controller board is connected on and select it.
- Set the baud-rate for 115200
- Reset the controller board and connect.
- Use the menu provided over the terminal window to access the evaluation board.
mbed microcontroller and AD5677R evaluation board
Hardware setup
Quick start
- Connect the SPI lines from the EVAL-AD5677R to the SPI lines of your microcontroller board. If your microcontroller is compatible with the arduino xxx form factor, then you should be able to just plug your microcontroller board and the EVAL-AD5677R together.
- Connect your micrcontroller board to your computer.

Introduction
The AD568xR are quad, 12-/14-/16-bit buffered voltage-out
DACs. The devices include a 2.5V internal reference (enabled
by default) coupled with a gain select pin giving a full scale
output of 2.5V (GAIN=1) or 5V(GAIN=2). All devices operate
from a single 2.7 V to 5.5 V supply, are guaranteed monotonic
by design and exhibit less than 0.1% FSR gain error and 2mV
offset error performance. The devices are housed in a 3mm X
3mm LFCSP and TSSOP packages.
The part also incorporates a power-on reset circuit that ensures
the DAC output powers up to zeroscale or midscale and
remains there until a valid write takes place.

Signal Picture
This is the CN-0196 Lab board. You can change the capacitors by resolder ones up to 50V specification instead of the used 25V electrolytic ones.
