Forum Post: RE: TSW1400EVM: TSW1400EVM + DAC902EVM : no SYNC out
Andrea, The triggering function does not exist for the code in CMOS mode so you cannot setup the board as either a master or slave. I am not that familiar with the source code so I cannot answer the...

Harald, If you are measuring the overall power consumption of the whole board, we need to localize this extra current to the ADS7142 before we dig further. Could you measure the drop across R104 to see...

Hi Naoki, I couldn't get a very definitive answer from the design team as this is an old part. However, what I got to know from them is that sometimes the internal biasing circuits have temperature...

Adam, Let me check this with the team and get back. What is the output load, by the way. can you try putting an RC load and see if this reduces. You can use something like 5K || 200pF Regards, Uttam
