DAC38J84EVM: How to output DC on DAC38J84

David Suh

Part Number: DAC38J84EVM

Hello,

Is there a way to output DC by supplying a constant data to the DAC? I can apply a constant and mix up to a higher frequency, but I'm unable to see just DC on an oscilloscope.

Thanks

David,

If you have a transformer in the output path, it will not pass DC. You need to monitor the DAC output directly with the both outputs properly terminated (50 Ohms to GND).

Regards,

Jim

Ah okay. I see the transformer on the DAC eval board. Thanks!
