Part Number: ADS1298R Tool/software: I have buffer[4000] to get data sample. When i place electrode (10 electrode) on body, my rawdata is constant=32768, and i can't fix it. Do you have any ideal for this case?
Hi Jejomar,
I worry that measuring all electrodes individually with respect to an externally generated VCM will degrade the system CMR. In post processing, computing the differential lead (i.e. LA - RA) should theoretically cancel VCM from the result…
Part Number: ADS1298R Other Parts Discussed in Thread: ADS1298 Tool/software: Hi TI support.
We've built a device using the ADS1298R and have been operating it at 32KSPS without issue on the digital side.
When performing a characterization of gain…
Part Number: ADS1298R Other Parts Discussed in Thread: ADS1298 , Tool/software: Dear Sir/Madam,
I am planning to introduce the ADS1298RIZXGT chip in my design and provide dual supply for the analog part (AVDD = +2.5 & AVSS = -2.5V) and +1.8V for the digital…
Hello Thuan,
I'm not familiar with the simulator you are using, but it looks like you are only measuring Lead I, Lead II, and the chest leads. Are you calculating the augmented leads and Lead III, then comparing them to the simulator screen? This does…
Tool/software:
In the ADS129x family, a 4-bit DAC is used to set the lead-off detection threshold for the positive and negative channels inputs. The DAC settings are configured writing to COMP_TH[2:0] in the LOFF control register. The threshold voltages…
Part Number: ADS1298R Other Parts Discussed in Thread: ADS1292R , ADS1298 Dear Expert
We are now designing a 12 lead ECG+RESP+anti defibrillation interference product using ADS1298R. Could you please help us check the issue with the principle design. Is…
Part Number: ADS1298R Other Parts Discussed in Thread: ADS1298 Hello,
I am trying to communicate SPI ADS1298R with ESP32 where I could find library supporting it?
Hi Nivethitha,
1. Yes it should be ok if the micro's in-built ADC meets the performance spec. of ADS7042 and so long as you can take care of any digital noise from the MCU is getting coupled into the system.
2. The RLD amp is used as a feedback loop…
