Other Parts Discussed in Thread: DAC8554EVM , DAC8554 , ADS1274 , ADS1174 , ADS1147 My name is Ivan and I am a researcher that works in a Neurosciences Lab with biological signals.
I write directly to you because I haven´t been able to post anything…
Ok, I think I can summarize everything I'm seeing. My previous observation that the glitching depended on the Vref voltage was wrong. With the Eval board, I had the OPA627 negative rail at ground and that hides the true glitching when the signal gets…
Other Parts Discussed in Thread: ADS1174 , DAC8554EVM , DAC8554 , ADS1274 Hi,
I have built a system with a DSK6416 + 5/6 Interface Card + ADS1174EVM + DAC8554EVM. I am now able to input values with the ADS1174 and output them with the DAC8554. I set…
Hi Ivan,
The ADS1274 cannot accept negative inputs - you'll have to maintain your signal in the 0-5V range. The differential input to the ADS1274 is +/-Vref, but that is at a common mode level of +2.5V. The DAC8554EVM can be configured to output 0-5V…
