Zedboard Digital to analog converter (DAC)

Former Member over 9 years ago

Hi

I want to purchase the zedboard for my application.

I Have to interface a conditioning circuit at DAC output.

Kindly let me know what is the output voltage of DAC.

Hello SDR1,
The ZedBoard does not have a DAC circuit on the main board. You can add a DAC interface by using one of the PMOD expansion headers or the FMC expansion connector. The FMC connector is a Low Pin Count (LPC) interface, so make sure you select an expansion board that works with the LPC pinout if you use the FMC interface.
The the interface between the ZedBoard and the PMOD interface is set to 3.3V. The FMC interface can be set to 3.3V, 2.5V, or 1.8V, based on the position of the VADJ jumpers on the ZedBoard. The interface between the DAC and your signal interface will depend on the interface PMOD or FMC board you choose.
Maxim has several PMODs with DAC outputs:

Analog Devices has both PMOD and FMC boards with DAC outputs:

And there is a list of FMC boards on the Xilinx website. Be careful to select one that supports the ZedBoards LPC FMC interface:
