Part Number: DAC37J84
The DAC37J84 is a two channel complex output DAC. Is it possible to operate the dac in non complex mode and have four independent outputs? If so is there an app note that details how to do this?
Yes you can. If you download the DAC38J8xEVM GUI from the website under the DAC37J84EVM product folder, you will see there are options to bypass the digital processing blocks and send the raw data directly to the outputs. See the attached file for an example with the DAC in this mode.
In reply to Jim Seton:
Is it possible to use the mixer to up convert to four real dac outputs?
Is there an isolation spec between the DAC A and B? The spec sheet shows isolation between DAC A/B pair and DAC C/D pair.
In reply to Tim Korsrud:
Two channels share a NCO so you cannot drive 4 DAC with 4 different NCO settings. I will look into the isolation question.
