DAC3171: Does spike noise occur structurally?

Yorihiro Sato

Prodigy 20 points

Part Number: DAC3171

I evaluated the DACs of other manufacturers. The result was unacceptable regular noise glitches. After checking with the manufacturer, there was a reply that the automatic calibration function periodically generated noise of several millivolts. Does the DAC3171 have a built-in function that causes such glitches

Hi Yorihiro,

Can you give me more details on your test setup and where these glitches are appearing?

Dear Miguel Lomeli

I will remind you that this is not a problem with DAC3171 but a problem with another company's product.

If there is no similar problem with DAC3171, I would like to use it instead

The test environment is as follows

Hi Yorihiro,

DAC3171 does not have a calibration function. On page 21 and up of datasheet we also have spectrum plots.

Hi Miguel

I did not see any waveforms that seemed to be a problem with the DAC3171EVM, but I checked them just in case.

I will start making a prototype from now on

Thank you
