DAC5681Z: How to increase output gain.

Aiden Lee

Part Number: DAC5681Z

Tool/software:

Hello all,

I'm using DAC5681Z to make a frequency, however the output power is small.

So, I'd like you to tell me how to increase the output power.

I want to generate 10KHz sine wave (one tone).

Below is my snapshot image.

Hi Aiden,

Try a higher output frequency, the ADT4-1T+ transformer as a low end BW of 9MHz.

Or switch out the transformer that can cover a lower frequency range.

Passing a 10kHz signal thru the ADT4-1T+ won't work.

Regards,

Rob

Hi Rob,

I fully understood your explanation, so I tested with 10MHz.

Below is a snapshot.

Thank you.

Hi Aiden,

Maybe try a little higher. If that doesn't work. Please send over a block diagram detailing your test setup.

Regards,

Rob
