Hi Reed,In your scope captures, it looks like you only have 31 clocks, can you verify that? From the 3rd to 4th picture, it almost loooks like the LSB got clocked around. Is that output data going...

Page 0, register 60 controls processing of the audio signal for the DAC. However, a miniDSP program requires a large number of register writes. I recommend using the output of Purepath Studio...

Mr. Asaka,TI does not have EVMs populated with the ADC14DC080. The easiest method would be to work with a PCB re-work contractor in your area to have the ADC changed on the EVM. The ADC device may be...

View ArticleForum Post: RE: ADS5407 Vcm output drive strength
Hi,The VCM output has 2 K ohm series resistance, (due to ESD protection reasons) so the drive strength of this pin is less than normal. Much less. For example, if you wanted to hold to within 100 mV...

Hi Marek,4.7k should be fine, but you could try 2.7k to see if that makes a difference. If you send me pictures of the layout I can check through it to look for any possible issues. You might also...

View ArticleForum Post: RE: DAC8564, DAC8562 and DAC7564 - unable to output 1 mV
Hi Stefan,The problem is that the output amplifiers in the DAC need some headroom from their rails. 1mV from the negative rail is actually pretty good, operational amplifiers that just get within 100mV...
